Basically using particle emitter to emit trees for a forest. Problem is they emit to close to each other making it look messy is there anyway I can make the particle system detect the other particles emitted and not collide with each other when emitted. This is being done using hair(needed) and heard about dynamic paint but couldn't work out how it can fix this issue.
I think you could set a big size to the particles
And then use the Molecular Script addon and enable the Activate Self Collision option.
