Skin weighting is always another tedious process I’m trying to speed up. I tried the new Delta Mush in Maya 2016 but there is no way to transfer the weight from the deformer to skinCluster. People are writing their own plugin to do that https://vimeo.com/106647863
Webber Huang shows a great tool and workflow in the video https://vimeo.com/130998850. I installed it but sadly it doesn’t work for my character with ribbon limbs setup.
Recently I’m using the smoothSkinClusterWeight plugin by Brave Rabbit, which already help speeding up smoothing a lot. Hopefully I could use it some day. Skinning is a not a fun task always.
