I’m trying to replicate the default formula of the Formula Deformer in Xpresso: Sin((u+t)*2.0*PI)*0.2. With the “2.0” and “0.2” part wired to user sliders.

But running into some roadblocks: 1) Plugging the the variables back into the formula math. 2) How to get the U data from UVs (if that’s what the default math is using). 3) Resulting deformer is moving the entire model in a sine pattern, not rippling out to individual polygons/points/edges.

Would appreciate some help. Maybe I’m overthinking it?
