Well my current problem, is what if I have to take a blender mesh into sculptriS ( I can’t get comfortable yet sculpting in blender), then back into blender to work in edit verts etc., then into UE4. Blender back into UE4 has been no issue at all, as I just used the mesh ( once I got it into position that is where I needed it to be <very complex placement for this mesh> ) as is in and back out to UE4 never any problems, but adding sculptris to the mix is again causing problems.
Its because when I import into sculptris I have to scale it up more to be able to work on it properly ( camera aperature I think ), then back into blender and scale is way too big as expected.
Would you addon allow easier workflow between sculptris <> blender and keep scale, or if not, what do I need to do to solve this hassle 
Well I grabbed 2.73 from official blender download page, so if they are the same, then I guess its the combination of cpu and gpu for me, or that my GPU is amd ?
It may also be that my mesh is much larger than anything you’re currently working on, mine is at about 150K.
