Good but the Pattern of the foam doesn't change, very disturbing.
Let’s check out another useful Houdini tutorial from Entagma. This time, we’ll learn more about blending smoothly between a high-poly mesh and its low-poly representation.
Blending smoothly between a high-poly mesh and its low-poly representation is a subtle but useful effect. In this tutorial, you’ll learn how to create two versions of the same object, one smooth and one facetted, with the exact same topology. This enables you to blend between the two using a falloff value.
We’ll use barycentric coordinates to interpolate the low-poly falloff values and transfer them to the high-poly mesh and then mix the positions and normal with VOPs.
Discuss the effect in the comments below.
