Finally there is a “flip” blendshape function in Maya 2016 ext2. Before that I have to create a flipped mesh first, and then assign the extracted to the blendshape target. This is the only reason I’m switching to ext2 so far. Their sculpt brushes are weirdly slow so I’m sticking with Shape 3.0‘s Brush tool and looking forward to the support of latest version. The new pose space deformer is confusing to me and the lack of shape extraction means my tools are still valuable !
Responding to the maya camera to AE shake test I did before, I’m sure it works. This is a handy workflow that you could have the shake quick in playblast and still be adjustable in post. Closeup and distant layers may need different amount of shaking to look right.
