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]> wrote: > Just one shader.
