Hi,
Question for some Python guru: what material value to change to put some numbers in highlited zeroes in x file exported from blender?

    Material x_material1 {
       0.655172; 0.458621; 0.196552; 0.299383;;
       62.745098;
       0.157471; 0.314943; 0.472414;;
       <b>0.000000; 0.000000; 0.000000;;</b>
      TextureFilename {"x-texture2.png";}
    }

That’s valuable information for my programmer who want to control some of variables in that way.

Edit:
It’s emissive, case closed.
