Stephen Mann shares a technique for connecting BlendShape Channels to a separate control where it’s still easy to toggle the connection.
Check out this new tutorial from Stephen Mann that shows a method to connect and disconnect Blend Shape channels in Maya easily.
Adding an intermediate control or node for Blend Shape channels can be helpful when starting to animate or rig, especially when you are still working on Blend Shapes. You may need to remake blendShape nodes, but you don’t want to lose connections or animation.
Mann uses his ChannelTools script for Maya to assist with the process.
