Version 4.0 now out!
Grab a copy, and paint NVCloth vertex colors like you never have before in blender
Additionally, this and many future updates are brought to you by Epic’s Mega Grants

The future updates will include:
Root motion adjustments.
Twist Bones for Thighs, and Wrists.
A new Metarig generation to help with sculpting new characters, and a few other bells and whistles that I have been wanting to add in for convenience (including the grass height to vertex color generation script, while i’m at it :P)
Enjoy
