How do you make a lot of noise in Cycles? I have a scene where I want a lot of noise, but noise generated by cycles, so it is coherent with the colors behind. Thus, I want to generate a lot of noise in cycles without using things such as noise textures. Can someone give me tricks to have a lot of noise naturally created by cycles for a scene with a relatively small object count?
To have more cycles noise just render with less samples and have glossy materials. Make sure reflective caustics are on, that will give you fireflies.
