How can I emit particles without them overlapping each other? How do I make a particle fit perfectly around a torus without absorbing or immersing each other in blender particle system. I made the torus the emitter, and use the sphere as the particle. I have tweak the particle number and some other things. Is there any other way I can achieve this?
You can use the Grid distribution to place the particles regularly over the surface. Increasing the associated 'Random' setting moves each particle by a random amount giving a less regular appearance if desired.
