so, as mentioned in my previous post I have a simple soft body sim of a sphere hitting the ground and I need it to emit steam. I got it all working but I’d like to module the surface a bit to break things up.
If the volume were static I’d multiply a PerlinNoise node with it, but since it’s moving, the volume (ball) would be moving through the noise.
I’d like it to stick to the surface though (which is deforming).
So in other words, I have an animated sphere emitting steam, but I only want it to emit from random areas on it’s surface not everywhere.
Can I texture it with a noise and use the texture values to drive where steam is emitted?
Now that I’m writing up the question I feel like Matt or Ronnie showed me how to do this in the past - but I can’t remember.
