export groom_root_uv to unreal 2024年10月8日20:45

To anyone else looking for a solution besides the Labs Unreal Groom Exporter.

1) Before the ROP Alembic export make an attribute wrangle with this code:

float u = f@groom_root_uv;
float v = f@groom_root_uv;
v@uv = set(u,v,0);

2) Then delete the groom_root_uv attribute with an attribute delete or some other way.

3) Import the saved-out cache into Unreal..

I honestly have no idea why this works, but it does.
