I’ve been trying for 3 days to make a simple Maya Xgen Groom to move in UE5.1 with a groom cache. But UE5 keeps crashing and crashing while trying to put the groom cache in the groom, in the sequencer
These are the steps:
-I bring the groom alembic exported from maya inside UE5. It has the groom curves and the guides. I followed the documentation, everything is fine on this part. They have their attributes(group_id, etc).
-I create a sequence, I add a blueprint that has the groom asset.
-And this is when things go south: as soon as I try to attach the groom cache to the animation slot for the groom asset, UE5 crashes. Some times I was able to do it, but then, there was a huge gap between the character geo and the groom hair roots. I dont have those gaps in Maya.
Is there a updated workflow to do this in UE5.1. The documentation is outdated and is not clear. It skips a few key areas that a less experience TD/Artist would struggle to follow.
Hi @osmeldu!
To solve your problem I’m prbably way too late, but did you manage to make it work in the end? My guess would be to attach the groom cache in the BP itself ( where one can put the binding asset as well).
I downloaded your files and my UE didnt crash, it worked pretty well.
But I was hoping, that you might explain how you managed to export the cache with animations and guide groupes? I’m following the documentation as well, however when I try to export an alembic with animations, Maya skips the guide groups… So I’m probably one of those less experienced TDs
Thanks in advance! and I hope your project went well!
I think I tried using the cache in the BP, but I got some crashes too. Also, is not pipeline friendly. In multiple shots it might be counter intuitive to change the cache per shot.
But I was hoping, that you might explain how you managed to export the cache with animations and guide groupes? I’m following the documentation as well, however when I try to export an alembic with animations, Maya skips the guide groups…
I cant remember right now, but I had to edit and combine the script in the documentation. Basically the guides group need their guides attribute to it, and the grooms groups and curves needs their attributes too.
and I hope your project went well!
