Maya flip normals vs reverse normals. ; Select the Meshes → Flip normals option from the menu.


  • Maya flip normals vs reverse normals Normals define how model’s surface will be affect by light source. 8. My guess would be yes, because flipped normals To reverse face normals and vertex normals and then extract the vertices, choose Selected faces then extract. &nbsp; I can select the instance What's New in Extension for Autodesk Maya 2014 What's New in Autodesk Maya Getting Started Basics Managing Scenes, Files, and Projects Data Exchange Environment Variables Modeling Normals > Reverse Normals > Conform Normals > Soften Edge Normals > Harden Edge Normals > Set Normal Angle Color Polygons nodes You can achieve what you want without solving the issue in the question. Select the curve and choose Edit Curves > Reverse Curve Direction. Normals are less likely to reverse when a file is of uniform size. Polygon Black Face Problem in MAYA | Fixing Black Face Normals | Fixing Normals in Autodesk MAYAAfter importing an object from other software or when doing The reason I would like to do is because I have used planes to model the base of my level. i did a lot of negative duplicates, so the normals get inverted [sometimes arbitrarily :confused: ] To fix this, you’ll have to select the item in question from the Subtool Panel under Tool, then head to Display Properties and choose Flip. Similarly, it is asked,how do you flip a surface in maya? Today, we'll go over how the Align Normals and Reverse Normals work inside of Cinema 4D. You can use the Polygons > Flip tool in the UV editor to flip a shell back if you need to. Unlike face normals, they are not intrinsic to the polygon, but rather reflect how Maya renders the polygons in smooth shaded mode. 法线 > 顶点法线编辑工具(Normals > Vertex Normal Edit Tool) 法线 > 设置顶点法线(Normals > Set Vertex Normal) Hi! I created a new nurbs surface patch by performing a Boolean Difference operation. If you do a set to face and then average normals, then do an Unlock Normals, you'll see that your mesh has gone back to hard faced, because the actual geometry normals weren't modified. Example in the images below. Some outward but 500/900 are now blue. Improve this answer. Welcome to the Autodesk Maya Subreddit. i think your normals might be facing the wrong way, select the faces, and in the normals menue select reverse normals from the drop down menu, i'm not sure what you used to bake out the normal map, but if you did it in a third party softwaye like xnormal, topogun or even zbrush then you will need to export out the low poly model out again (having reversed the The flipped vertex normals resulted in errors for some further analyses. ) The direction of U and V isoparms on a surface determines the direction of the surface’s normals. Now its normals are truly inverted so now you can reverse the normals and finally delete the history. To avoid creating non-manifold geometry, use In this tutorial, we’ll explore the concept of normals in Maya, covering the essentials of softening and hardening edges, as well as techniques for displayin Note: The Reverse option can result in non-manifold geometry, where polygons that share an edge have reversed normals. Applied a Lambert material and exported again, works fine! I noticed that one of the trouble maker meshes has YELLOW vertex normals, while all the other meshes have GREEN vertex normals. Is there a way to flip just the uvs inside out since the normals are fine? You could also try to combine 400 plus seats with bad normals and flip them. Velusion. Like this example. The Sub Tool panel is a bit like the scene outliner in “sane” 3D apps. If you can provide a picture I should be able to help more. co/selectflippeduvsOriginal script from TITANius from Cg Society. I've found a couple posts about this after googling, but none of them seem to show a reliable solution. When he selects all the faces and presses Reverse, the cube shows the inner side of its faces, Maya Questions; Programming; normals [state] Maya Questions; Programming; normals [state] You will get a nastygram warning parts have become inverted and the -1 scaled part will turn black. 0. During his film experience, he's worked with Maya on movies such as Alien Covenant, Pirates of the Caribbean, Venom, Pacific Rim: Uprising, Batman V Superman - Note: The Reverse option can result in non-manifold geometry, where polygons that share an edge have reversed normals. Looking to figure out duplicate special instances and how scaling an object (to flip it) affects the normals (Using Maya 2015, Student Ed, MacBook Pro OSX 10. freeze transforms (now the normals are inverted) 3. Concept Art By Benedict Ne The Maya Toolbelt by Michael McKinleyA tutorial going over the Reverse command in the Mesh Display menu (Maya 2023)!Music is by Lino Rise - Channel Intro Hon As you perfectly explained, I needed first to . Unless Stingray doesn't honor those settings, I FlippedNormals Q&A - We answer most of your questions. Simply select the faces and hit "Flip Normals" under Mesh Edits. These can look fused as one normal on connected smooth shaded geo, but will split and follow the face normal when flat shaded. That means that if you've watched all the episodes up until this poi The only solution I found is to split the part into a uvgroup and then isolate it and use display>flip to reverse the normals. take your object and go select element under editable mesh and select your entire object's faces. Follow answered Mar 28, 2018 at 10:28. Your instructor, Henning Sanden, has worked in Maya for a decade. 05-04-2006, 04:46 PM. Reply. Move your cursor over the Face Normals tab and another menu will replace the original one. Select the surface and choose Surfaces > Reverse Direction > and choose the surface direction to reverse, or swap to swap U and V. With screen space in the camera view: The X axis runs left-right perpendicular to the camera viewing angle. vladimirjp. They are often used as a way of specifying which side of a surface points “inside” or “outside” (for example, when creating shells). /difference", "needs_reverse", 0) After the end of the loop, create a Normal node. Select the curve and choose Curves > Reverse Direction. View Full Version : normals then you flip the normals that the dot product was negative this might work, but I'm not sure. Share. yep was having the same problems too, saved alot of time cheers andreseloy and Bingo.

Four tutorials all about the importance of vertex order for reversing and correcting normals. If you have the "shade UVs" option enabled, Maya will show flipped UV shells in red instead of blue. You will likely need to mark the mesh as convex in addition to flipping the normals, and may need to split it into 2 hemispheres. So typically when importing a mesh, they will come locked. To avoid creating non-manifold geometry, use the Selected faces then extract option. 2 has been updated ! It is now working for Maya version 2017 to 2023+! if you have any feedback or bug reports mail me at : [email protected] Installation: It is possible to flip normals for any single face. Figure 3: Figure 3 shows that after Reverse the direction(s) and normals of a surface. You will notice that you need to change your vertex normals if you try to extrude a face and it ext In this video I will show you a simple technique that repairs flipped normals on an object that has already been skinned and animated within Maya You attempt to catch everything in an animation pipeline, however, there may be times when one tiny think has snuck by mostly everyone on the team, such as the normals being off in a character model that has Either reverse your normals by opening the uv texture editor and reversing then there, or fillp them in photoshop and when you apply them in maya they should be flipped the right way. Normals also define Then I imported everything in our engine and saw that the SSS was acting weird so I re-checked everything and saw that some uvs are flipped. What do you think? Also, I have been having problems with all the normals flipping (and the mesh becoming "black") when I duplicate with -1 X, then freeze transforms. I'm pretty sure there is an if i do this to a group i need to revese all the objects of the group, one by one ,and cant do reverse to all the group at once. Name: maya_locked_normal Class yea, the state [or directions] of my normals matter a lot. You can launch the Flip Normals tool either via the Tools section in the Ribbon or via the context menu in the Real-time View or the Scene This dockable script for maya is just basic functions I gathered together to speed up my modeling tasks. comic just reverse the normals in Max or Maya. The Normals Render Element uses screen space to determine the colors in the render element. In part one, we focus on polygon wi We're hitting this problem where things flip while following a curve, either as a motion path or as a spline ik. Select V to reverse the CVs along the V parametric direction. scroll down to surface properties, there is some option there for the normals, one is to flip selected, the other is to unify selected, which would make all normals face one way, if they all become faced inwards then you can use flip to reverse them. You need this to have correct Normals not just correct point order. 0 Likes Link copied. Hi, help always appreciated, I'm a new user. I just modify it for easy selecting the flipped UVs. scale -1 to flip 2. But no matter what i do to the model, ZBrush always inverts the normals. I know things like spine IK's and motion paths have up vectors, but that can sometimes cause more problems than it 法线 > 顶点法线编辑工具（Normals > Vertex Normal Edit Tool） 法线 > 设置顶点法线（Normals > Set Vertex Normal） Description. In which case you need to select all the blue polygons on your mesh and type in “U-R” or the “reverse normals” command (which is right below the align normals command in the same menu above) Either way, what you want is a mesh that only I averaged the normals of matching vertexes for two separate meshes to smooth the normals between each mesh in Maya. This option will split vertices so as not to create non However, I am very familiar with Abraham at Nexttut and found his channel to be the most relevant help I could find on many topics. Autodesk Community > Maya Community > Maya Modeling forum > Normals then go to Edit Mesh > Reverse? Reply. I'm having a bit of an issue with UV's at the moment and had a question: Is it possible to reverse / flip UV's without affecting the normals? the mesh I'm working on has correct normal display but UV's are flipped (red), and I can't reverse one without affecting the other. Turned out I had a normal map applied to the model in Maya and this was being displayed in Accurig, looking 'flipped'. Select the surface and choose Edit NURBS > Reverse Surface Direction > and choose the I need to do a boolean subtraction between two models in C#. Delete from convex hull all faces with normals orientation equal to normals orientation of the original face. Versatile Extras : "Miscellaneous" offers a range of handy tools, from "Bake Pivot" for permanent pivot adjustments to Here we create game assets using various software like Autodesk Maya, Mudbox, Zbrush, S #mayatutorial #3dmodeling #mayamodeling Welcome to my channel 3DWolf. faces: Note Reversing the surface normals (Polygons menu set: Normals > Reverse) is useful when you want to change the surface direction (that is, whether the surface is oriented inwards or outwards in relation to the model). For correct rendering, do I have to explicitly reverse the direction of surface normals on back faces, or does the OpenGL subsystem automatically do that? EDIT: Coming to think of it, if I reverse their normals manually they will become front faces and will be culled. The normalConstraint node will orient an object towards the closest available face normal. Every vertex has its own normal. Hey Guys, in this video learn Reverse Normals tools Maya 2023 don’t forget to check out my channel. Under the Mesh menu, click on the Normals option, then click “Recalculate Outside” (hotkey: Ctrl+N) or “Recalculate Inside” (hotkey: Shift+Ctrl+N). ; Notes. I'm having an issue with my normal maps where they appear inverted in render, but normal in the viewport. To avoid creating non-manifold geometry, use the Select faces, then extract option. The Lathe modifier sometimes creates an You can visualize the split normals (per corner normals) in the overlay while in edit mode. This is represented in the Red channel of vrayRE_Normals with 1 being left-facing geometry and 0 being right-facing 82K subscribers in the Maya community. The only solution really is to duplicate the mesh, reverse normals, and then I'll have two layers of geometry to fake it being double sided. Anonymous. Snake Advanced Rig for Maya 2022 •Forward FK/Reverse FK Controls •Roll and FallOff for Smooth Rotation on FK •IK Controls with Individual Twist •Forward FK and Rev FK snap •Slider control to switch between FK and Reverse FK •Path Fk and IK Controls •Varialble FK •Variable Reverse FK •Auto Slide (zigzag) movement on path Now after doing this I found that the normal's are obviously flipped, so I click the Reverse button under the Normals menu. How do you fix your normals in Blender 2. Select the surface and choose Surfaces > To access the option and/or correct an inside-out or inverted face, first select the errant mesh element in Edit Mode [1] (using vertex, edge or face) and from the Mesh menu It flips all normals, similar to reverse. 05-04-2006, i could easily write a mel that reverse them. Use Flip Normals to reverse the direction of all selected faces. However, if I simply reverse the normals, the petals on far side won't show because they are Vertex normals. ; Select the Meshes → Flip normals option from the menu. In this manner,how do you flip a surface in maya?

A normal is the direction that is perpendicular to a mesh surface. Some models I need to reverse the normals of for example when I duplicate an inner wall and want it to keep the same shape as an outer wall. Match face normal. Flipping the normals of an object turns it inside-out. The resulting direction of the surface normals will be based on the direction that is shared by the majority of the faces on the mesh. Flipping Normals. How do you change the vertex in normals? Select the vertices and choose Mesh Display > Vertex Normal Edit Tool. But this will be slow and performance heavy if I have thousands of cards Flipping faces Maya Modeling. Tried reversing my normals and still looked broken, couldn't figure it out. July 3, 2019, 3:20pm #11. I wanted to post a simple breakdown of the face weighted normals method in Maya as i usually forget stuff like this so thought i'd keep it here. dave Avatar Challenge Winner 2010 The direction of U and V isoparms on a surface determines the direction of the surface’s normals. Instead, the normal don’t Reverse polygon normals Select the faces you want to reverse:Select Mesh Display > Reverse > in the Modeling menu set. For a clear indication of the orientation of the faces of mesh objects make sure Autodesk Maya 2014 Extension 法线 > 反转(Normals > Reverse) 法线 > 一致(Normals > Conform) 法线 > 软化边(Normals > Soften Edge) 法线 > 硬化边(Normals > Harden Edge) 法线 > 设置法线角度(Normals > Set Normal Angle) 颜色 gum. When Match face normal is set, the vertex/face normal value is matched and locked to its current face The Flip Normals tool allows you to automatically or manually reverse the direction of the normals on an object by selecting its faces. But all the normals are ok. PROBLEM: When I duplicate special, and duplicate the object in an instance but the object is flipped, the normals are reversed. To do this I have used Color Composite and Ai Nor In this class you will learn about00:52 - Face Normals03:50 - Reverse Normals05:30 - Conform Normals06:08 - Vertex Normals09:55 - Average Normals12 To flip the normals, hold shift and right click to bring up your marking menu. Reverse the direction(s) and normals of a surface. I might be an exception, but when I came back to Maya, I was able to pick the program back up very quick. Flipped normals youtube channel is good too, but the videos tend to get drawn out longer than what I want. I've displayed my normals and tried every Reverse Surface Direction Option. Addressing an issue with inconsistent normal direction in a model, and showing how to correct it in Maya. This is a quick tut on how to change your vertex normals. Reply reply This video helps in combining/Adding/Mixing/blending two normal maps in Maya software with Arnold Renderer. Especially dealing with some dirty CAD models imported to Maya. I checked for flipped UVs, any overlap, face normals, What's New in Extension for Autodesk Maya 2014 What's New in Autodesk Maya Getting Started Basics Managing Scenes, Files, and Projects Data Exchange Environment Variables Modeling Reverse polygon normals Displaying hard edges in customized colors Deleting and simplifying polygons Using the Crease Set Editor I've written this code for my game and what I want is to flip the normals on a texture in unity. Select Swap to exchange U and V parameterization. Both involve keying/changing the U and V parameters to drive the movement along the surface. In Maya, normals are used to determine the orientation of a polygon face (face normals), or how the edges of faces will visually appear in relation to each other when shaded (vertex normals). So I need their normals to be facing the right way. "Normal Bake" streamlines normals transfer between meshes. I noticed this discrepancy when trying to extract normals on an object whose vertices are on the seam border with another object. Reversing the sequence of CVs for a surface reverses the surface normals. Have you tried selecting the faces of the surface you want to invert, then go to Edit Mesh > Reverse? Normals are less likely to reverse when a file is of uniform size. batFINGER batFINGER. Click Reverse Normals. Training & Courses I'm having a problem with faces flipping backwards and Normals<Reverse isn't working. 2). For example, duplicating a surface across its axis of symmetry can reverse the surface normals on the duplicated surface. edit. Hi! If your object turns completely black after lightbuild it has problems with its lightmap (usually not existing/wrong uv channel!!) and not normals usually when you have flipped normals your mesh/faces starts to glow/emit light!! anyway you should be able to fix it in your 3d app!! In Unreal usually what can help is to uncheck use mikktspace in your object’s . Frustrating with a couple thousand polys normals now randomized. If normals are flipped in the program of origin, they will invariably be flipped in Maya. If your objective is to achieve same result for front and backfaces of same gemetry and normals. Normals; Components of NURBS curves; Parent topic: Step 2 Setup of Normal. I have a model and a texture and wish for the texture to be inside the sphere model and not on the outside. A normal is a theoretical line that is perpendicular to the surface of a polygon. Select one or more mesh objects. your second question is something that showed up on my computer a while back and it was Reverse normals doesn't work as expected. If you just want the face alignment, you can position your object and then create and immediately delete a normalConstraint. Use an Attribute Delete node to delete the unnecessary attributes. Object. Related topics. also some rendering issues i have with inverted normals. reverse the normals. After a decade I am still looking for a better and faster way to reverse flipped normal. So I'm asking again if anyone knows. The al en este video explicaré como solucionar un error causado por las normals en maya. User Normals Specifies whether or not user-defined normals are affected by the Reverse operation. Usage. Normals also define hope you're all doing well. 8? How do you flip your normals? In this video I go through how to do this in Blender 2. 4. As a result, I have to manually flip the normals to make them pointing similarly to normals of the template face. Following your suggestion, I created an array of pairs (that would be the "edges", right? a-b, b-c and c-a) of each face. You need to flip normal in shader in case triangles are in opposite direction than normals were calculated For a complete solution I needed to reverse the order of my verts array so that the winding is opposite of what it was Autodesk Maya 2013 Extension 2 法线 > 反转(Normals > Reverse) 法线 > 一致(Normals > Conform) 法线 > 软化边(Normals > Soften Edge) 法线 > 硬化边(Normals > Harden Edge) 法线 > 设置法线角度(Normals > Set Normal Angle) 颜色 Under "Attributes", you'll find "Nrmls" which allows you to edit the Normals of the Mesh. Related topics Edit the vertex normals to Hi, So I'm trying to select faces which have their normals flipped. c The edges surrounding the vertex face are hardened if it is possible to do so, and the normals unlocked. fbx into Unity and view in the scene, I don’t see the same smooth normals that I created in Maya. im doing a lot of dynamics which requires normals to be pointed out to calculate.

Subscribe to RSS Feed; Have you ever wanted to split a mesh without having a noticeable split seam in the normals? If so this free Maya copy normals tool is for you. Trying to reverse the other surfaces ends up Step 2 Setup of Normal. Vertex normals determine the visual softness or hardness between polygon faces. This option splits vertices so as not to create non-manifold geometry. To reverse face normals of all (selected or unselected) faces in the shell, choose Select the face, hold shift+right click, on the right side of the menu you should see face normals, go into that menu and select reverse normals Maya reverses the normals on all (selected or unselected) faces in the shell. The only difference between Raw and the default Srgb is that with the latter, I get weird shading, but the detail is inverted either way. Note The Reverse option can result in non-manifold geometry, where polygons that share an edge have reversed normals. Usually you can just ALT click a sub tool to select it, but that doesn’t work when the normals are flipped. It also includes 240 normal maps that you can use in various programs such as Substance Painter, Substance Designer, Mari, or any texturing software. ) This product contains 240 alphas for your projects, inspired by a sci-fi and cyberpunk style. Note Reversing the surface normals (Polygons menu set: Normals > Reverse) is useful when you want to change the surface direction (that is, whether the surface is oriented inwards or outwards in relation to the model). With the "Normals" Menu removed from the Maya Hotbox, Solved: With the "Normals" Menu removed from the Maya Hotbox, how do I flip faces? to get the correct face to show (not show black, but. SimplyMaya. Rather than exporting the same model twice but with the normals flipped I would like to know if can be done in UE4. You might look at doing your own collision detection. None of the options (U, V, Swap, or Both) seem to affect the normals at all. Flip Normals is found on the Surface Properties rollout and on the Normal modifier. July 3, 2019, I have a UV unwrapped object that I want one part of to show its texture flipped horizontally, but I can't seem to find a way to do this other than flipping the normals, but I'd prefer not to do th For beginner to intermediate, there's usually 2 solutions that are fairly digestible. Specifically, I am hoping that a user, by flipping a surface in Rhino, can cause a reversal of its surface normal in GH. Modeling Box v 1. If normals are flipped in the 1. gumroad. If so I hope someone can assist me with the problem. The maths should be pretty simple for this case: assuming sphere is centered at the origin, if the distance to the center of the thrown ball >= (sphere radius - ball radius), you've collided. My goal is to bake all these xgen converted cards to a normal map. Selecting an item a second time using the same direction restores the original CV sequence. I've taken the OBJ back to maya before sculpting taken the same OBJ that ZB inverts, back into maya, set The problem is I flipped the character 180 in Y axis then realized that it wasn't the way Might need to reverse the normals as well Maybe you can try using the bonus tools of Maya, in Animation you have the option of mirror. I haven't found any way to edit those. Put this face into convex hull. If you wish to only flip certain faces of the mesh, use the "TriSel" Mode under "TriModel" instead. com/c/FlippedNormals?sub_confirmation=1 detail(".

(A) Attach a follicle to the NURBs surface and constrain the object to the follicle. This option will split vertices so as not to create non Ensure that the scales for each imported object are fairly similar. They are often used as a way of specifying which side of a surface points “inside” or “outside” (for Hey man, old post but thought I'd throw in 2 cents since I had the same issue. Select the surface and choose Edit NURBS > Reverse Surface Direction > and choose the surface direction to reverse, or swap to swap U and V. All 3D software compute vertex normals in their own way(Max/Blender averages last I checked, Maya has face weighting on by default) and you can further edit these vertex normals. Move your cursor over the Flip Normals button and it will flip the normals In this Maya tutorial, you will learn how to add a texture to the backside of your single-sided polygon using Maya Utility Nodes. The Mesh FlipNormals command reverses, flips, the normals of mesh objects. Here is the result maya should now correct the normals on negatively scaled geometry when the normals are frozen. One of the meshs will be entirely within the other mesh, so I was hoping to reverse the normals for the one model and add the two models I have just imported a model I made from maya 2008. the face selection mode and hold shift and right click and then select face normals and then from the sub menu select reverse normals. x = -1 also reverse the normals since three.

We share and discuss topics regarding the world's leading 3D-modeling software. This way I get a seamless look with the benefit of being able to switch out the head mesh with variations. IIRC its the middle icon under normals. The image is self explanatory and makes it look more long winded than it is, the actions performed were simple menu options but i've condensed them into two simple scripts that can be kept on a shelf or assigned to hotkeys for speed. I've tried setting the 'Mesh Component Display' to Full seen here and then marquee selecting but it selects the faces anyway. The follicle node has a U and V parameter which can be keyed to move along the I found a script on the forums (created by Phlip) for flipping the normals of multiple objects at one time, but the syntax is for 2. Welcome to SketchUp's home on reddit: a place to discuss Trimble's easy to use 3D modeling program, plugins and best practices. Ensure that the desired model itself is of high quality and ready to be imported. comhttp://www. The Average normals does not, it creates smoothing groups and locks the normals, which can cause a lot of issues when trying to transfer to other programs or edit the normals further. Click a flair to sort by topic and find a wealth of information regarding the content you're looking for. youtube. You can see the stamens not display correctly, because the normals of petals is pointing into the middle of the flower. Basically I used the Mesh > Mirror tool on parts of my mesh, and when importing into Substance Painter and baking light, some parts look darker, like they have inverted normals. I've set the bump node to tangent space normals, and the color correction of the file to Raw. 9. Issue: How does one reverse normals in Maya on a larger scale than manual selection?Many objects have too many faces to individually select and are misaligned after the file is imported into Maya. I just want to know how to invert the normals of this "hair" (I don't know what this is named the normals of this "hair" (I don't know what this is named, probably NURBS, I really. how can i reverse the normals of all the group in one action, and not piece by piece? Quote Reverse the direction of a curve. Thanks in advance Note The Selected faces option can result in non-manifold geometry, where polygons that share an edge but have reversed normals. I already applied this solution in my answer here: Is extrude possible in Geometry Nodes? #ShortsIn this tutorial we show you how to identifiy if the normals need to be flipped, how to view the face orientation of your normals in object mode, how Hi All, I've had this problem before and posted up on here i didn't really get a resolution to it, other than my own work around. In the Maya preferences, under Modeling, you can change maya's polygon tangent space to be right handed or left handed. mergeVertices() to have unique shared vertices between faces. That should (re the title "How to flip normals") In edit mode, select the faces you wish to flip normals and . Anyway to get around this? Normals Color Generation. I have a model that i created in maya, and want to sculpt detail on in ZB.

The normals have been averaged in maya using Normals > Average Normals from the Polygons menu set. Report 0 Likes However, if the normal is flipped, there's a decent chance whatever caused it (ex, negative scale to mirror something) also flipped the UV shell, in which case the texture will be flipped too. I know it's difficult without an example object, but I'm hoping somebody has seen this problem before. how can i reverse the normals of all the group in one action, and not piece by piece? The flip of an object with a negative scale object. The black sections end up facing out but the rest of the model suddenly has reversed normals. There are several ways to invoke the command: Press the Flip normals button. maybe start with 100 objects, it might be too much calculation on 400 at once. 6? Here is the code: import Blender for obj in Blender. When I render, some of the objects on my character look black. Normals are a mathematical side-effect of NURBS. This is the default setting. The problem seems to be that the normals on the CV's flip if you rotate them too far in one axis.
