As shown in the 2 image previews I made a simple setup from the rubbertoy with hairs.

I can layer animations from Houdini and the hairs get perfectly fine deformed/transformed. But when I import the rubbertoy in Maya (doesn't matter if I imported it as an USD or OBJ) and then export it as a .usda file I get really weird offsets on the roots of the hairs, when sublayered to the original asset.

In the attachments you can also see it has the right hierarchy, the USD settings and also a hip file.

What makes it even more interesting is that if I use a sopmodify and unpack the purpose:render geometry to polygons the issue suddenly disappears. But this beats the purpose a bit considering the speed of USD.

The reason I want to import the usd from maya is because of animation purposes ofcours. Also .usd, or .usda doesn't make any difference.

Kind regards,
Chris
