(4-26) Groom Binding Asset Bug

Hi, everyone. I’m having an issue with keeping binding assets attached for grooms. Every time I reopen my file the grooms are detached.



Usually I would just reassign the binding assets, render and call it a day. Unfortunately even if I re attach the binding assets, it still appears broken in my render. Some will be attached and some won’t.

Render:

In the movie queue render you can see that the eyelashes are floating. Am I missing something here? I’ve googled and scoured this forum for days but I haven’t seen this question answered. Thought it might be the way that I imported my grooms so I stepped back and went over the that again while following the documentation as closely as possible. I would really appreciate some guidance on this. I’m absolutely stumped. Tested this in both 4.26 and 5 early release, but the issue persists. This is in the MHC lighting preset project if that makes any difference.

And seems I found a root of this problem.
If you are using MHC lighting preset, just delete these line from DefaultEngine.ini:

r.HairStrands.AsyncLoad=1
r.HairStrands.BindingAsyncLoad=1

Can confirm this bug. Same here with UE5.02 and Metahumans. Also MHC lighting preset was used.
