Object exports with another object's geometry

I have a scene where when I render with Renderman, one of the objects incorrectly uses another object's geometry instead of its own geometry. I can share the scene if you can send me a link to where you want me to upload the file (email is on my Github profile).

You should be getting an e-mail with a BOX folder link shortly. Please upload this one and the one for #692 .

I have uploaded "painter9-buggy.blend", which should demonstrate both this issue and #692.

  1. In IPR, object "ceramic2" and "ceramic8" take on the geometry of "tarp2"
  2. Object "Split Diopter" triggers issue #692 (but I think #695 fixes that problem)

Thanks. I will merge in your change for the index error.

With regards to this issue, are you on Windows? If so, do you have "GPU Subdivision" turned on? If it's on, try turning it off and see if you get the right render.

If you do get the right render, this is a bug on the Blender side (https://projects.blender.org/blender/blender/issues/111393). I committed a workaround fix for it, though, so double check to see if your local version has my change: 8fe492f

Makes sense, the problem objects all had a subdivision modifier. I am on Linux and turning off GPU subdivision does fix the issue.

The dev branch also does not have this problem.
