This is Couture for Maya, I had this script on my shelf for months, but now it's ready for a release !!! :)
Couture is a simple script that ease the clothes retopology workflow.
Couture will take care of all the redundant tasks (create blendshapes, wraps, etc..) that you can encounter when you're trying to have a nice and clean mesh from a scanned garment or from Marvelous Designer.
I wrote this tool in python, mostly pymel but also some Maya API thanks to my good friend Rémi Deletrain.
Last but not least, this tool is completly free for you :)
You can download it right here, right now ! :
