Hello! I learned that we can use blendshape and wiredeform to make expressions in Houdini. Besides these two ways, are there any other ways to do the expression? And i used to use the cluster tool of Maya, with which i can have real-time operations directly to points, then the shape can be changed. So my question is, does Houdini have similar tools? Thank you!

Clusters are really just Houdini bones with a 0 topheight and bottom height.
