I posted on cgtalk but I thought I’d cover my bases here
So I have 2 heads with same topology but modeled into different likeness and have the same UV’s. One has blendShapes and I want to transfer the deltas over to the new head. I’ve got it mostly working by using transfer attributes using UV space from the head with blendShapes to the head without and then applying a blendShape from a duplicate of the head # 2 to put it back into the original state.
Where it breaks down is for example the eye blinks. On the first head, the lids close and hit their marks. The head with the transferred attributes and corrective blendShape, head #2 eye blink doesn’t hit the correct shape. I know it has something to do with the delta offsets in relation to the 2 meshes but I can’t seem to wrap my head around it, sort of speak. I feel I need to calculate some sort of scale factor from corresponding points in order for them to hit the same shapes.
Any suggestions?
