texture with xgen alembic grooming? density maps don't working?

It does have different uvs that previous groom versions but still wrong

I think I found what is going on. I tried with a simple plane as you did and I got the same result, no problems at all. But with the gorilla is different, when I import the groom it seems to be inverted on the X scale, but seems to be a thing from maya cause I tried with different Unreal versions and it’s the same result

hello! is there any one know. how to create custom attributes (like width or length)??
