POV-Ray export questions

[Roland Melkert]

You defined the textures in the model using texture{} directly inside each object{} statement. Instead, it should have a material{} statement at that level, like this:
Other material definitions include the interior{} statement for transparent objects, using a good interior makes all the difference in making transparent objects look good.

the reason for that was the texture_list property of mesh2, but I think I'm going to split it into texture and material defs so both can be used.

edit, made some changes to the generator it now renders this 'out of the box' (which I'm very happy with).
   

Colors are now generated like so:

Code:

#macro ldrawTexPlastic(r, g, b, a)
pigment {
 #if (a<1.0)
  srgbt <r,g,b,0.9>
 #else
  srgb <r,g,b>
 #end
}

normal {
 bumps 0.005
 scale 0.5
 turbulence 0
}

finish {
 emission rgb colorEmission
 diffuse 1
 brilliance 1
 conserve_energy

 phong 0.5
 phong_size 40
 metallic 0
 
 reflection {
  rgb <0.08, 0.08, 0.08>
  falloff 1
  exponent 1
  metallic 0
 }
}

#end

#macro ldrawTexRubber(r, g, b, a)
pigment {
 srgb <r,g,b>
}

normal {
 dents 0.01
 scale 0.25
 turbulence 0
}

finish {
 emission rgb colorEmission
 diffuse 1
 brilliance 0.1
 conserve_energy
}


#end

#macro ldrawTexChrome(r, g, b, a)
pigment {
 srgb <r,g,b>
}

normal {
 bumps 0.01
 scale 0.1
 turbulence 0
}

finish {
 emission rgb colorEmission*0.1
 brilliance 6
 diffuse 0.7
 metallic
 specular 0.80
 roughness 1/120
 reflection 0.8
}
#end

The contents of ldrawTex* macros are read from a config file so you could always tweak them, I'll probably also going to surround most stuff with 'if defined' conditions.

Transparent part improvements (using material) still pending though.
