Should I use Zbrush, Substance 3d or 3D-Coat? I am notlooking at sculpting models from scratch. I need to make changes to 3d models downloaded from say Sketchfab, then paint and import to Character Creator 4. Ihave had a play with ZBrush but it is not intuitive due to its very non-standard interface etc. I can see it being a long learning curve. IsSubstance 3d or 3d-Coat easier to learn / use and would either be suitable for what I am trying to do?
