Some time ago I wrote a MEL script for saving out skinWeights for massive from maya skinCluster. Script writes out weight is massive’s native format (.w file extension). Massive is crowd simulation software and is used for giving artificial intelligence to crowds and make them believable. Its common practice to skin character inside maya and take out skeleton ,mesh (as obj) inside massive for doing crowd sim. But we have to either skin it again inside massive which is defiantly not very intuitive or import weights from maya. So this script makes this task easier by writing out weights in separate file from maya itself.
