It seems like the problem of https://github.com/princeton-vl/infinigen/blob/f98b9575c73c322f1cbcc2dd48d26bbe8d6239f6/infinigen/tools/export.py#L523

When I replace export_usd with True the export is fine.

However, I cannot find the vertex color information in the exported .ply and .obj.

David-Yan1 commented 3 weeks ago

The bug is indeed caused by some of the objects being set to invisible in the blend file, which requires slightly different handling of visibility while baking. I have a patch that fixes this that will likely be out soon.

should be fixed by v1.3.4
