These last 2 days, I ve been working on integration particle vs particle collisions on SPARL
The result is quite good so far but not perfect yet. But I dont really think I can make it a lot more realistic without killing performance.
Particle vs particle collisions will be integrated in the release to come. It will simply be a modifier to plug to the group to activate the collisions.
Here is a small demo illustrating what Ive got so far. It runs well but I can still optimize the process I think :
demo collision particules contre particules
The controls are the same as the flakes demo.
