USD Alab

Hej,
Did anybody had sucess with importing the Alab USD file from animal logic into unreal 5.
I am able to import the geo and also switch between proxy and highres, but I am not seeing any textures. I followder there instructions to copy the highres textures by hand into the fragment folder but its still not working. But it should. :smiley:
Am I missing something. Did somebody already got it working?
Any tip would be highly appreciated.
Thanks.
Sebastian
