Been working with a scene for over 7 hours. Spent only 10 minutes setting up the terrain, and fire pit with coals, but the flames. I want nice flames. Real flames. 7 hours later, on the 12 revision (total rebuild of cloud setup) and I have something resembling a campfire's flame. Ray marching is ramped up to a whopping 10 for the smooth "rippling" verticle effects like the flame has a source.
