Well, that’s the best way to put it. I was following this fire tutorial, and it worked, at least closely enough for me to start tweaking things on my own. Primarily, the fire particles were just too big, I needed finer flame. So, I went to the particle system, and modified the particle size. I… may or may not have made some other adjustment to something, I honestly don’t know. But suddenly, all the particles are shaped as slightly rounded but quite distinct cubes, and they end up forming a wall of sorts. Fascinating, but not the intended effect.
I’ve tried restarting the program, as well as playing with all sorts of settings, anything that I figure I possibly could have touched between “round” and “cube”, to no avail. My last-ditch effort was to discard my work by deleting and recreating the particle system and domain. But, despite definitely being the exact values I had when things were “round”, they’re still cubes! Is there something I might have hit elsewhere in the object settings, outside the particle systems, that could have such an effect?
