Stephen, I’m fairly sure it has nothing to do with UVs. But I’ll try to get the log. What I’ve discovered is that if I extract pieces of the mesh away from the outer perimeter, paring it down till it reaches about 250x250 units and no bigger, the problem disappears. Breaking it up into quadrants that way solves the problem for the time being. Thanks. Joey

Hi You don't mention whether you checked the Arnold log for warnings. If it was tessellation errors, then you would see it with or without a texture. You can try using the Utility shader (Primitive ID with polywire) to check that. The Utility shader also has UV modes for debugging. On Fri, Jun 1, 2018 at 11:01 AM, Ponthieux, Joseph G. (LARC-E1A)[LITES II] <[email protected]<mailto:[email protected]>> wrote: Just one shader. Its using a custom UV set for a single texture that I don’t dare touch since the UVs are generated automatically by CityEngine to repeat sidewalk segments along the sidewalk artery. Since other renders have shown they can handle them, I don’t think it’s the UVs. There are over 900 shaders but there are thousands of objects in the scene. Shader application by CityEngine appears to be incredibly efficient. Yeah It looks like I’ll probably have to call them. I can hack it up in the short term but there is something in this scene that Arnold just doesn’t like. Or that the scene doesn’t likeabout Arnold. Its procedurally created and exported via FBX and then imported to Maya. It rendered fine in Mental Ray but I’ve had no end of difficulty with it and Arnold. Ugh.

How are the different shaders applied to this single object? Is it using face sets? There is a cap of 256 shaders per object if that is the case.

(LARC-E1A)[LITES II] <[email protected]<mailto:[email protected]>> wrote: I have found one workaround so far that seems to force the render to behave. The geometry is procedurally created in CityEngine. The offending geometry in the scene is the “sidewalk” object. But the way it is generated is that the entire sidewalk is like an arterial system created as one object for the entire scene. Its really large, and is very oddly shaped. But the geometry appears to be fine. The Maya Software renderer handles it just fine. What I seem to have discovered is that if I break it up into smaller segments the shading bugs go away. Its almost as if Arnold is applying a smooth shading override to the surface. Even though I’ve set normals on the surface to face, applied hard edges, every attempt to modify normals in some substantial way has failed to affect the shading bug. Incidentally there are other really large “organs” in this scene. But they are comprised of smaller groups that are disconnected from the other groups but still as one large single object. They render fine. It only seems to be an issue with large objects with contiguously connected elements. Does anyone know what gives with this? Is Arnold trying to do something special that affects objects of immense size that are contiguously connected?

Nope. First thing I checked. CV counts at each vertex are 1. There is no non-manifold geometry that I can find related to the objects with the anomaly. Besides, if it were the geometry, I would expect that removing the texture would not remove the anomaly. If there is no texture, the bug is not present.

(LARC-E1A)[LITES II] <[email protected]<mailto:[email protected]>> wrote: Howdy yall, I thought I would post here before I escalate this but… Arnold on Maya 2018 is producing an error in render… I’ve got an ESRI City Engine scene imported into Maya 2018, It was working fine under Maya 2017 and rendering fine in Mental Ray. But mental Ray is gone now. 1. It renders in the Maya Software render fine. 2. In Arnold it produces what looks like triangulation (Tessellation) errors rendering some triangles darker than others. 3. It only produces the problem on materials with texture maps. 4. Disconnecting the textures from the diffuse color removes the problem. But removes the texture also. But this seems to indicate its not a lighting, normals, or shading error. 5. I’ve turned literally everything in Arnold settings off or neutral and no change. 6. Its not shadows, nor anti-aliasing, nor duplicate polygons, nor a bad mesh. 7. Forcing a triangulate on the mesh can make different triangles darker but the problem does not go away. 8. All reflections, shadows, motion blur, etc have been turned off in Maya and Arnold for Render Settings and Object. No change. Any thoughts? Thanks Joey ------ Softimage Mailing List.
