Hi! I’m new to UE, and I’m trying to create a custom MetaHuman Character, including hair. I created some hair for my MetaHuman in Blender, using this and this tutorial. However, I’m not able to create a Binding Asset for my grooms. Whenever I try to, I get a pop-up saying “Building groom binding data” with a progress bar, which is perpetually stuck at 0%. It is using my CPU though, so it seems to be doing something, but it just never progresses or finishes, not even after letting it run for 30-ish minutes.
I have tried to resolve the issue with the solutions I could find online (for example), but nothing has worked so far. Any ideas on how to fix or workarounds that would still allow me to use my hair on my MetaHuman would be greatly appreciated!
SOLVED: Turns out the origin of the hair was too far from the target mesh. I found this out by dropping both assets in the level and resetting both actors to their origin location. The hair dropped in at world origin, while the head was sitting way up on the Z axis (where a head would be). The result is that the groom roots are not in the expected position relative to the target mesh, so the binding cannot properly find the correct vertex indices and keeps looping through all vertices to search for nearby ones. I was able to fix it by going back into blender, setting the location of my hair to where the head would be in Unreal, applying transforms, and then after exporting and importing the binding completed quickly.
Hopefully this helps someone out in the future. Thank you all for your help!
