Gas_Fire 1.7

This simple shader will give you a 'gas fire' like look when applied as a material.

There are two things you have to do when applying this shader:
- open the fractal node in the render tree and choose a texture projection to apply displacement.
- turn up the displacement step in the geometry approximation of your object.

Other settings :
- A two colour mixer lets you control the colour ramp of the 'flame', so it could go from blue to white for example.
- Animating the 'time' parameter of the 'fractal node' will animate the 'flames'. a slow setting of .3 increment per 25 frames seems okay.
