3. Zbrush + Keyshot plug-in with Keyshot Bridge. Total price is less than Keyshot PRO, but it works completely as Keyshot PRO, exept import feature. So you can import only through Zbrush and work only with Zbrush-supported formats. OBJ format is ok, so it could be good for someone.

Hello,

It might work if Zbrush could understand vertex normals from imported .obj, but it wasn't the case few months ago.
So you have to export really dense mesh from MoI to keep the result acceptable (but not perfect), and that's a pity because you can't take any advantage from MoI meshing engine.
