Hello @csyshing, I wanted to let you know that we have fixed this issue on our end. Feel free to test and let us know if you come across any other issues. I am going to go ahead and close this ticket out for the time being.
Describe the bug Hi,
We have a production asset that some parts of the geometries disappear, it turns out that it was causing by "uniform" interpolation opacity which mayaUsdPlugin doesn't seem to handle correctly.
Due to IP issue I am not able to provide a repro that you can see it visually, but here is a super simple repro USD file (basically a plane with "uniform" opacity):
I tried to put some debug output around here: https://github.com/Autodesk/maya-usd/blob/dev/lib/mayaUsd/render/vp2RenderDelegate/mesh.cpp#L1743-L1745
The example USD above,
alphaArray
has just 1 element which matches the raw primVar declared in USD, our production asset is more complicated but essentially the same as above.If you need more info, please do let me know! Thanks, Zhicheng
