Just a quickie post; the copy menu script is now in bf_extensions SVN on blender.org. Some updates: It can now copy Vertex weights by index and it can also copy mass ( a request on this log) thanks to Fabian Fricke. I’ve also updated it to work with current SVN, which means… yes, it won’t work with Blender 2.53 beta anymore. It’s a fast paced Blender we live in! I’ll try to make it work in both soon, but no promises.
