Random rotation on child particles? Is there a way to have a random rotation on child hair particles? I know you can have random size, but if there's a way to randomize rotation as well that would be great.
The "Random rough" parameter of the children seems the only one that affects individual children without too much correlation between them¹. Unfortunately though, it inevitably affects sizes too. Also, it can't be constrained to the normal axis (in case you needed it):



3 hair particles, 4 children each

A real "random rotation" doesn't exist for children specifically.

¹ (if "Size" is small enough)
