I just tried following this tutorial. So I was using the two versions of mark which were included with the software, one with the animation and one with the blend shapes and when i tried to set up the blendShape solver i got this message:
2023-07-19 15:43:45 [Warning] [omni.usd] Warning (secondary thread): in ProcessPropertyChange at line 519 of C:\b\w\ca6c508eae419cf8\USD\pxr\usdImaging\usdSkelImaging\skeletonAdapter.cpp – Unhandled ProcessPropertyChange callback for cachePath </World/male_bs_46/joint1/bs_anim> in UsdSkelImagingSkelAdapter.
But the animation is transferred. When I do the same using my own models I get the same error but the animation is not transferred. Anyone have any idea why this could be? Thanks.
