What it be: Syncnix Blender Lip Sync Addon! Blender lip sync shape keys are driven by tool for seamless and smooth transitions so fast that you’ll ask yourself, why tf would I use blender lip sync rigging? Syncnix is the closest we are to having blender auto lip sync animation.(Even more-so with the next update)
Lip syncing in blender might have been a struggle before.. but never again.
TLDR: Lipsyncing sucks, Syncnix lessens that suck.
What it do: Add the tool, link your model and youll have blender animating speech for your character faster than you can say weight painting who.
