Milkshape 3D 1.8.0 has been released today.
http://chumbalum.swissquake.ch/ms3d/download.htmlThe big new features are :
* Support for vertex weights (you can now assign and view vertex weights in MS3D).
* COLLADA file format support.
This means MS3D users can finally work on models from HL2 and other modern games without loosing their vertex weighting (causing the models to deform unnaturally during animation).
