Support static meshes with multiple material elements

[Animalgel]

Current functionality seems to be limited to material element 0. Many static meshes have multiple material elements. Would be great to be able to automatically generate textures/materials for each slot to maximize texel space.

Workarounds seem to be separating the static meshes in external software (maya, blender, etc...), reimporting the separated meshes to unreal, generating textures/materials, manually assigning automatically generated materials to material element slots in combined mesh...

Reasonable request. I'll prioritize this. Thank you.
