Tires in POV-Ray

[JGW3000]

I am doing some rendering in POV-Ray, and I am overall pleased with the results. Most parts have nice reflective surfaces; however, I found that non-reflective parts, especially tires, are rendered as shiny objects. Is there a means to have only tires rendered in a matte-finish, so as to give a more realistic appearance?

Tires should be using ldd_part_material_dullRubber. It is possible, that for some new tires this material was not assigned as part material. You can do it by adding:

#declare ldd_part_materials[NNNNN] = ldd_part_material_dullRubber;

to your pov file. NNNNN is part number from LDD.

Of course it is possible, that the definition of ldd_part_material_dullRubber is not good enough. Try to use custom version of ldd_finish_dullRubber_255. It is declared as:

#declare ldd_finish_dullRubber_255 =

finish {

ambient ldd_ambient_light_color

#if (version>=3.7)

emission ldd_ambient_light_color

#end

diffuse 0.4

brilliance 1

phong 0.1 phong_size 10

specular 0.1

roughness 0.15

reflection 0

conserve_energy

}

#declare ldd_normal_dullRubber_255 = normal { bumps 0.1 scale 0.016 turbulence 0.2 }

Feel free to experiment and if you improve the definitions, please, share the results.

Hrontos - thanks, the "#declare ldd_part_materials[NNNNN] = ldd_part_material_dullRubber;" statement in the .POV file did the trick. For the record, the tire part is #11209
