S10 Q1 full render!
Still has problems with particles going through each other.
Simplest solution is increasing npartical self-colliding radius however: because molecules are in vast different sizes, and we want to show the environment to be crowded -> how to make some nparticles bigger than others?
Possible solution via expression? Self-Collide radius vary via Custom Index #?
I have yet to find the code for it.....
Other potential solutions -> render in different layers? Use bullet system for the front most particles -> better collide calculations but longer rendering time.
Rest in the background -> use nParticles + blur.
Proposed solution: use different emitter for different nParticles :
write creation expression for RadiusPP
StartFragmentif (nParticleShape1.emitterId == 0)
radiusPP = 0.2;
radiusPP = 1;EndFragment
PROBLEM: how do I instance this...
