This is a fire layer from "Flame Thrower" Fluids page before composited. Fluid emitter's heat and fuel was created with high turbulence, turbulence, swirl and a low viscosisty value. High Fuel scale and reaction speed. Texture time was animated, and multiple color was created in texture incandescent. High frequency ratio, frequency and depth max to get more details with a Perlin noise type. Volume axis field was parent constrained to the emitter object with high magnitude. Fluid Shape's Turbulence strength was keyframed to breakup shape pattern. Real lights, pointLight, spotlight, and raytrace shadow. Rendered with Mental Ray with base resolution of 100.
