Instead of doing this, create a polygon selection and use a copy of material without displacement, or correct the uvs, and paint with 50% gray the parts that should not be affected by displacement.treddie wrote:OK...I think I know what is going on, maybe, anyway.

Not a direct answer to your problem, but be aware that polygons outside of the usual 0-1range still have UV coordinates, just not within the default area most apps assume as default. "No UVs," and "Non 0-1 UVs," are not always handled the same way across various programs.treddie wrote:OK...I think I know what is going on, maybe, anyway. I placed the non-displaced mesh polys outside of the UV area in C4D to get those polys out of the way. As a result, their UV coords are black. Could Octane be getting screwed up trying to calculate mesh areas that have no UV coords? But that would not explain why the button part is getting messed up too.
Thanks, Frank, for the info. It at least explains part of the improvement I see now that I moved those parts back into the 0-1 range, and painted with 50% gray. However, although the texture problems seem to have cleared up, the black triangles are still there and C4D says the normals are fine:Not a direct answer to your problem, but be aware that polygons outside of the usual 0-1range still have UV coordinates, just not within the default area most apps assume as default.
