I’m using 5.7.1 creating new metahumans from the MH asset.

Al looks fine until after Assembling. The BP’s hair goes crazy:

I’ve tried multiple metahumans and hairstyles, longer hair and beards are totally fritzing out. This a bug?

Double post, I think it may have been a bug going from 5.7.0 to 5.7.1, can anyone confirm? Yesterday I had a metahman built in 5.7.0 project, assembled fine:

I reopened that same project after updating to 5.7.1 and opened that same MH character asset and Assembled it again with a different name, and the hair is blown out this time:

So, hopefully someone has a solution?

edit: I just opened a fresh 5.7.1 project and tried to assemble a metahuman and have the same issue, so it’s not an upgrade issue

I tried removing the groom binding and reattaching, no help.

However I found that if I used the groom binding that I made when the project was still 5.7.0, it works.

So 5.7.1. seems to have broken groom bindings?

Yup. Same problem here. Meta human that was created yesterday with 5.7.0 worked fine. I created a new one today with 5.7.1 and it has the same problem.
