Noticed this has been an issue since the release of your material editor (which is a wonderful addition btw). Due to the lack of depth sorting things like hair pieces that rely on multiple meshes are destroyed upon import.
Is this something that can be looked at? Sorry if this is more a suggestion than a bug, I’m even more sorry if this an error on my part. Haven’t seen anyone else on the workshop manage to pull it get this working correctly either.
This is a limitation of the translucent materials in Unreal Engine. What you’d want to use to solve this is masked materials. I can expose that as a setting. But, masked materials lack any gradients.
