You may have a look at the patch below (use any texture on the quads) before reading on, but I’ll try to explain it here.
What I want is that when a new pair of XY coordinates snaps in, the powder start from the coordinates and fades away with distance. Then, when these coordinates are removed, they have to be gradually remove from the spread, when bangs on the LFO+Change are detected.
Think of this application on a multitouch table. When a blob is detected, it has to generate powder from the finger. Then, when another finger is detected, it has to start generating powder smoothly.
The nodes hidden are just for testing.
If you guys don’t get what I am trying to do, I can explain it again.
Thanks in advance.
