I exported the abc file from Maya XGen using my script. If the precomputed groom_guide_weights and groom_closest_guides attributes are used, only UE5.3 can recognize them. In versions higher than 5.3, these attributes are not read correctly, resulting in hair not matching its guides and some hair shaking violently.
Is this a bug? Or is there another correct way to use it?
It’s a bug
Thank you, do you have a solution?
