Short description of error
When a vertex group is used to control the density, particle systems emit from grid-like patterns, also emitting multiple particles from the same spots. This is most obvious in Hair mode of course.
Exact steps for others to reproduce the error
- Create two random objects to act as the emitter and the particle.
- Set up the particle system.
- Now paint a vertex group and set the particle system to use it to control the density.
