Resources for face rigging


I’m working on my character Lilac here and, having finished the fur, I want to revisit the face rig.
The rig I currently have can’t be pushed any further than the frown up, and the smiles don’t really work at all

does anyone know any good resources for face rigging?


for reference, this is what the frown looks like from the side

It’s one of the best resource out there, it’s quite lengthy but covers all you need to know for facial rigging,
from good topology to shape keys or bone based rigs.

All the knowledge is easily translatable to blender.

Thanks I’ll check it out=)
