HeightField Deform geometry node

Deforms geometry by a changing HeightField

This operation deforms geometry according to an animated heightfield. The points of the geometry will rise and fall according to differences in the rest and current versions of the terrain. Optionally, the points can also rotate to follow the changing slope.

This can be used to have packed objects float on a water surface.


Blur Radius

The heightfield is blurred this world distance before computing the change in height and slope. This averages out changes, the size of the blur should be roughly the size of the object that is being moved.

Rotate to Normal

Rotate the attributes of point, or the packed primitive itself, to respect any change in slope that has occurred.
