Exporting dense groom from xgen with root uv

Development Character & Animation

I am following the guide on exporting an alembic file of xgen hair with root uv to support textures from the epic documentation here

My groom is dense 300,000 curves, so when I first export my groom from maya then reimport (as per the documentation), I get several SplineGrps under the main group corresponding to the xgen description, eg SplineGrp0, SplineGrp1, SplineGrp2, etc.

When running the simple_hair_uv.py script and modifying curve_top_group to include all the spline groups, it hangs on export.

When I export a regular alembic file, not using the script, it works perfectly on export and import into unreal - but obviously I have no root uv support.

TLDR: has anyone had much luck exporting a dense groom using the root uv texture script for maya and it not hanging?

Thanks!

Hi, did you find any solutions to this. Iā€™m facing the same issue as well.
