Initial subdivision surface test scene. This one has some pyramids with edge and corner creases.

Just passing through to say that landing these assets would be much appreciated! However, I do notice that the sharpness values used are non-standard. The assets use values like 25 and 100 which are outside the expected range of 0..10 to match OpenSubdiv. These will be treated as infinitely sharp according to USD: https://github.com/PixarAnimationStudios/OpenUSD/blob/release/pxr/usd/usdGeom/mesh.cpp#L386

Thanks for the poke. @crydalch could you comment on the out of range values? perhaps an update is in order?
