I import my models, and that works, but the materials and colors on the model don’t appear in Unreal.
same problem here -.-
I think sculptris only exports obj and not fbx files, so they don’t work quite right anyway. (Unless there’s some new version that does fbx as well.) You can import your obj files into nearly any 3d modeling application and re-save them as an fbx file to make sure UE4 imports them correctly.
But you still need to click on the “show advanced tools” in Sculptris and save your texture/normal/bump maps and import those separately, make a material out of those in UE4 and then apply that material to your object and it should mostly look like it does in sculptris.
