To quote the original poster: I weight painted this shit manually so excuse any weird weighting hiccups I might've missed. Applies doubly here.
IVCS bones only, YAS bones will likely clip through the harness if scaled or moved around significantly. Fitted around YAB WC legs; Rue tummy will clip with the front retainer, though it doesn't look terrible.
The model is positioned slightly off (sits higher) than the skeleton bones and thus the weighted reference I used, so don't expect 1 to 1 transitioning of c+ presets and such - adjusting should be minimal though.
