I used a particle system on some text that I converted into a mesh. I'm very satisfied with the smoke, but the fire looks kind of "chunky" with a chunk of fire for each particle. I'm using a particle system with 200,000 particles over 85 frames.
I hate to infringe on anybody else's copyright (this picture is from this link) but this guy got a very nice "non chunky" fire effect.
What parameters can I change so that I can achieve this effect? (I'm using Cycles.)
