Hey Everyone,

I am currently going through Knipping's Applied Houdini Volumes Courses and he just talked about the concept of divergence in a volume sim. I am still a bit confused on exactly what it is though. From what I know its little pops and puffs in your volume sim. I was wondering if anyone could better explain the concept of divergence to me.

Thanks!

Try primitive wrangle, check “Do transformation” and put

rand(@primnum)*45

in the rotation fields.

So that seemed to work to be able to rotate the prims seperately, one more question, is there a way to set their pivot points to the center of each primitive instead of the centroid?

Hey Everyone!

Im kind of new to Houdini and I'm just trying to mess around with different things I can do with geo. I have this idea to take a polygon sphere and break out the primitives to be able to add rand rotation values to each primitive procedurally.

I have basically gotten the sphere created., I used a facet sop with unique points checked to separate all the primitives. Now I am struggling trying to find a way to be able to add a random rotation expression to each primitive individually so that each primitive rotates differently. In the end I want to create this sphere with each face vibrating differently.

Any Advice?
