Field Modifier node: controls, inputs and a free patch

Field Modifier

Runs your kernel once per vertex of an incoming mesh, letting you rewrite position, normal, color, or any custom attribute with plain math instead of picking from a fixed deformer list. Leave the geometry input empty and it generates its own points instead, acting as a source.

What it does

Field Modifier is a 3D node: it builds, changes or lights geometry that Render 3D turns into a picture. It takes 3D shape in and gives 3D shape out.

Try it

Write P.y += bass to turn any mesh into a shape that visibly pulses with the low end.

Controls

Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
