Description Kuehnhammer Tobias 2013-08-01 06:24:37 EDT 
Start a match. Change your player model to e.g.: 'Cadaver', 'Xaero' or 'Klesk/Flisk'. Do these commands: 'cg_thirdperson 1 + cg_thirdpersonangle 180'.
Fire your weapon. Parts of the model are not illuminated. Maybe related to specular shader?
All other settings are default, though if 'r_gennormalmaps' is enabled than even model parts are affected that use no specular shaders (see attached screenshot collection: Sorlag)

I've committed a fix, turns out the shader parsing code was letting through some shaders that used CGEN_LIGHTING_DIFFUSE without making them use the lightall vertex&fragment shader path.
