How to fake a facial rig by morphing standard face? May 26, 2023, 6:44 a.m.

So I see someone does this in Maya but I don't know Maya.
The idea is this

I have a standard rigged head mesh from metahuman, let's called it head S.

And I have a custom scanned/photogrammetry/sculpted head mesh(or even opened front face mesh only). Let's call it head C.

Their tricks
Morph, or project mesh S to C so that S match the shape of mesh C. (or at least its front part, the face match the shape of mesh C)

You get a rigged head that looks exactly like head C.

how to do this in Houdini? Can we use Ray node? I tried but I got uneven and wild floaty polygons around the edge of the mesh's open border.

Is there a way to scale the position of kinefx joints? May 16, 2023, 9:26 a.m.

I don't know why the length limit of the title is so strict..

I am learning face rig and trying to "suck joints to their centroid" in kineFX

so simple setup

I have rig character's eye to eye joints.

Now I want to all points to move towards their centroid, or move towards their mean Z-position.
In 3DSMAX you can toggle the "use common centroid" button and then use scale to to pull the vertices together.

But I cannot find a way to do that here. I have to manually move those joints, which is not efficient and of bad quality.
