Cant Find a 2D Circle for Unitys Particle System

Question

I have seen many people using 2D circles in unity's particle system but I cant find out how.

Thanks in advance!

Answer 1

in the renderer module you determine what the particles will look like. in the shape module you determine the shape of the emitter and you can select circle.

edit by changing material under 'Renderer' in render mode 'Billboard' you can change whats being rendered
