Has anyone been able to access multiple animations stored in a USDZ file through the RealityKit APIs?

Material Texture Tiling with Reality Converter

I imported .FBX file into Reality Converter of an avatar with clothing. Instead of the material pngs stretching around the mesh, they are tiled across the mesh, so all the texture shading looks like little dots. I thought it must be an issue with my imported FBX file, but when I bring the resulting USDZ into Reality Composer, then export from Reality Composer, I get all the correct png maps for each material and a USDC file with all of the correct textures applied. Any idea why these texture materials would be tiling instead of stretching around the mesh?

Building openUSD.org toolset on Big Sur

Trying to build openUSD.org toolset on Mac Big Sur beta. Make file blows up about a third of the way through the process. [ 35%] Built target hdTiny_headerfiles make[2]: * No rule to make target /usr/lib/libm.dylib', needed by pxr/base/arch/libarch.dylib'. Stop. make[1]: * [pxr/base/arch/CMakeFiles/arch.dir/all] Error 2 make: *** [all] Error 2 Looks like it is trying to find /usr/lib/libm.dylib which I think is supposed to be a symbolic link to /usr/lib/libsystem.dlib, but I dont think this exists any more on Big Sur. Any ideas on how to get pass this dependency issue? I think the system library has moved to the cache in Big Sur
