I have a 3D matrix of many objects and would like to use Billowy smoke to
change certain parameters of them, e.g. size, position-jitter, rotation etc…,
depending on the density of the smoke at these coordinates.

“More smoke -> more action.”

Or in pseudo-code:

Is there an easy way to implement this? Or is it possible at all?


Thanks

Oh wow, super easy as it seems.


Thanks a lot!
