Hi there,

I'm trying to produce a flame based upon a burning gas, but used for 
illumination.  I've come up with two different ideas.  Both of them don't 
put out enough light, and could use some work.  Any ideas?  This is 
designed for an outdoor lighting situation.

#1 is a blue bunsen burner flame

#declare BlueFlame = 
        union {
        sphere{<0, -0.3, 0>, 0.8
        hollow
        no_shadow
        pigment {rgbt <1, 1, 1, 1>}
        interior {media {emission rgbf<0.6, 0.6, 1, 0>//0.5
                         scattering{1 rgbf<0, 0.1, 0.8, 1>}
                         density{onion color_map{
                                [0.1 rgb <0, 0, 0.2>]
                                [0.4 rgb <0.6, 0.2 1>]//, 1>]
                                [0.75 rgb <0.8, 0.8, 1.45>]//, 0.2>]
                                [0.95 rgb <0, 0.1, 0.8>]
                                }
                                scale 0.8 turbulence <0.35, 0.1, 0.35>}
                                method 1
                                }
        
                }
        scale <1,4,1>
        }
        light_source { <0,-1,0>
                        rgb <.4,.2,1> 
        }
}

#2 is the same flame, but made red

#declare RedFlame = 
union { 
        sphere{<0, -0.3, 0>, 0.8
        hollow
        no_shadow
        pigment {rgbt <1, 1, 1, 1>}
        interior {media {emission rgbf<0.9, 0.9, 0.5, 0>//0.5
                         scattering{1 rgbf<.8, 0.7, 0.3, .7>}
                         density{onion color_map{
                                [0.1 rgb <0.2, 0, 0>]
                                [0.4 rgb <1, 0.5, 0.1>]//, 1>]
                                [0.75 rgb <1.45, 0.8, 0.8>]//, 0.2>]
                                [0.95 rgb <.8, 0.1, 0.8>]
                                }
                                scale 0.8 turbulence <0.4, 0.1, 0.1>}
                                method 2
                                }
        
                }
        scale <1,4,1>
        }

 light_source { <0,-0.3,0>
                        rgb <.9,.7,.1> 
        

}
