This torch fire uses standard noise, gradient ramp and falloff maps to realistically simulate the impression of a large-scale torch flame or 'olympic fire'.
This effect is independent from commercial third-party plugins, resolution and time scale (combustion effect continues endlessly).You may apply this shader to almost any other geometry, too, and thereby create a variety of different fire effects. Included as a bonus is one of my 9000x4500px resolution sky environment maps (also available through TurboSquid) [January 26 2005 Update: Download links for the necessary freeware plugins have been updated in readme file to make it much easier for you] |
