Looks very cool. May i ask, how many polygons does your TRex have? Because, my ZBrush can't handle so much details and i always thought, its would be because of ZBrush isn't a x64 Program.
Thanks and the Trex Was broken down into uv Tile's so i could break the model up into separate subtools and Subdivide more! also i used HD Geo on the eye and neck for added detail. but yeah 64bit Zbrush 5 i cannot wait to sink my teeth into !
