I am trying to make particles shoot up like a firework, put the particles are huge and look like a multicolored cloud. I tried the size slider but it doesn’t change anything, and I tried things in the material but still nothing. How can I make it smaller so it looks like sparks from a firework?
Does anybody know? I really need this in the next few minutes, please.
Welcome to world of disappointing particles. I too have found that the particle size slider does not do much also.
I am assuming you are using points as particles. Select the emitter, then the materials panel and click on halo in the render pipeline. Now you should be able to adjust the size of the halo in the shaders panel.
