Hi,

disable material settings in MED, set up a material in your code, asign it to your model in WED and change its values in SED as you want.

Code:
MATERIAL* mtl_mymaterial =
{
  ambient_blue = 100;
  ambient_green = 255;
  ambient_red = 100;
  diffuse_blue = 0;
  diffuse_green = 100;
  diffuse_red = 0;
  specular_blue = 255;
  specular_green = 255;
  specular_red = 255;
  power = 10;
}


Quote:
- the 4 MED windows show the content of the SED and I can`t do anything


mouse right button on any window -> Refresh Views

hope it helps you.
Salud!
