I am trying to convert a .glb file to an USD in order to use RealityKit.

I have to textured models which works well, but when I try a simple model with color only, I get some issues.

When I try to convert my GLB to USB using Reality Converter, I have an error. I tried to import the model into another software called Gestaltor, the import seems to be working, I have the colors, but when I convert it to USD, I loose all color information.

I put a link to the glb I want to use, so maybe someone can tell me why it's not working. .B4-UL01.1.glb

I expect the color to be displayed in USD format. I also expect Reality Converter to work instead of saying me there is an error.
