Join Jason Baskin for an in-depth discussion in this video Splitting symmetrical shapes into asymmetrical pairs, part of Rigging a Face in Maya.
…One of the challenges of creating a flexible library of blend shapes is…to build asymmetrical targets which can…be combined to create fully symmetrical complements.…For example, it's useful to have an asymmetrical left…or right smile, but animators also need to be…able to combine both of these shapes into a…full symmetrical smile with an appropriate shape along the mid-line.…Sculpting these sorts of complementary shapes by…hand is extremely challenging, but a relatively simple…solution is to take advantage of attribute…maps within Maya's Paint Blend Shape Weights tool.…
So here I have a symmetrical frown and I want…to split it into a left frown and a right frown.…And to do that I've actually taken this shape and fed…it into my left and right target shapes as a blend shape.…So you can see that each of these shapes as…an input, which I've activated 100%, that is the symmetrical frown.…And if I were to edit this shape,…it's going to modify both my left and my right targets.…So now I want to fade the influence of the symmetrical shape by going into the Edit…
