UVTools - part of the GameTools range - is a useful plugin that deals with the task of mapping and material creation on mesh and poly models within 3dsmax.
Now - in its third release - UVToolsV3.0 has broken away from the GameTools interface to have a radical facelift with a brand new looking user interface (view picture) !
All the original tools are still in their rightful places but have been completely recoded from the ground up and now - globally - except editable_poly meshes and standardmaterials as well as editable mesh and multimaterials offered in previous versions.
Tutorials will follow shortly.
