Vex and VOPs – A Twist Deformer

Now let’s do something a bit more demanding. We will replicate the twist deformer I made in ICE in VOPs, and then use some vex wrangles to allow a control object to place the twist deformation anywhere on the object in world space. Here’s the actual twist deform VOP, with a little extra to make the twist into a whirlpool funnel shape:

Pretty straightforward, the VOP takes a radius of points around the origin and pull them down in Y as well as rotates them around the origin, with a falloff based on distance and ramps to allow for user control.
