Detailed Description

Hi everyone! I have some usd models I created using Isaac Sim 2023.1.1 a couple of months ago. Currently I need to continue working with those models but apparently the new version of Isaac Sim has incompatibility with my files, they just crash when I try to upload them.

I have also tried to open the files just using open usd composer but still happens the same problem.

Anyone from NVIDIA that can let me know if there is any compatibility issues of .usd models between versions of Isaac Sim? Thank you

@delgad84 do you happen to have the crashlog reports/files you could attach?

The console error says: Failed wait for MDI material

Sure. The steps are just open the usd file in Isaac Sim from files. The cars models have materials, it should look methalic, not red. Here I included both files to be downloaded. Transfer "USD models" is available for download
