Take a look at the following teapot.pdf:
The walls around the teapot are lightned but it looks like the teapot is not lightned at all. The colors of the teapot are created by diffuse color array as described in ECMA U3D (18.104.22.168.3.5). So my question is simple. Is it Adobe Acrobat who does not apply lightning on objects colored by a color array and if so, why?
PS: I am asking to know if it is Adobe Acrobat's fault/feature or something else. I actually use IDTF converter created by:
so it might be that I just create the IDTF in a wrong manner.
