I’ve been playing around with the Mutable Plugin since upgrading my project to 5.5 and I really like what I’ve seen so far, but I think some features could improve it much further.
One thing is making many of the groom parameters into mutable parameters. Mostly I’d like to be able to change material parameters on the override materials, to easily be able to change things like hair colors inside the mutable system instead of having to do it in BPs. Hair color feels like such a basic thing to have in any character creation system.
Another thing I wish for would be an option to make the generated mesh a Nanite mesh. A bit odd to me that this wasn’t an option considering Nanite skeletal meshes were a big new thing with 5.5.
