Campfire VFX
In this project I wanted to see how well I could make a realistic small flame using mainly panning textures (rather than flipbooks). I used a flipbook that I created in Houdini for the smoke, but everything else was made from the two packed textures I 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
