I come from a Hexagon type modelling background and the more I learn about MoI the more I am truly amazed! (I have all sorts of programmes including Amapi7.52 through to the latest versions of LightWave andXSI)
Combined with the extra potentials for manipulation with the type of apps like 3D Paint and even the simple Vertex Room Displacement Painting of Carrara6Pro---what else do most of us need?
