Mudbox texturing for asset creation

I posted this here, hope I’m not breaking any rules posting it here as well since it’s to do with both UE4 and modelling. Having a really hard time finding the answer.

Related to asset creation - does anyone use Mudbox for texturing objects? I have a problem where projection painting using a 2k seamless texture map applies really low-res looking textures on my object, unless I re-create UV’s at like 15 tiles, but then the problem lies where exporting the FBX to UE4 gives 15 materials just for that one texture, and I have to sort through the exported UV textures from Mudbox and place them in the right spots, then make normal maps for them, and so setting up materials for a tree that is one part bark and one part leaves takes an hour because the bark material is split into 15 parts.

Sorry for the rambling, anyone have any tips?
