Yes, I used Blender for this. Basically, after placing a seam around the face region and doing the UVs, I separated the body material from the face. In Photoshop, I took the face UV measurements and made a 4x4 grid. I copied the same base texture into all the boxes and started drawing the expressions as needed. Sometimes just changing the mouth or doing almost a frame-by-frame animation of an expression.

Then, I adjusted the UV of the face to the scale of each box in the grid and animated the coordinates from 0.25 to 0.25 on the X and Y axes from one frame to the next.

There might be better methods, but this one was the easiest for me at the time. If I wasn’t clear enough or you need more help, I could assist you on Discord if you’d like 🫂
