Campfire VFX
A test to see how well I could make a realistic small flame using mainly panning textures (rather than flip-books). The only flip-book was for the smoke (created in Houdini). Everything else was made from two packed textures created in Substance Designer. One for the flames, and one for the overall shape -- both are scaled to 512x512 in engine.
Flame material -- made using a panning tiling texture and flame shape mask. The flame is colored using a curve atlas in engine
