WISP is an enhanced fire simulation shader. It takes your existing fire simulation and applies corrected shading to the volume, turning it into a magnificent rolling fireball. It provides better depth perception, visual fidelity and animatable burn control with no extra simulation cost.
The shader has been built on the foundations of simplicity and flexibility making it super easy to understand and customize to your own needs.
