I do not get much your code, where mat_model come from, no info from manual.
Also I have tried and nothing happen.
But I as guess, what you are doing is set ambient color of entity to full white.But this way required much job

From manual

Quote:

---

Total Light = Ambient Light + Diffuse Light + Specular Light + Emissive Light

And the ambient light only

Quote:

---

Ambient Light = AmbientMtl * ( PRV + EntRGB )
Where:

Parameter Description
AmbientMtl Material ambient color.
EntRGB Red, Green, Blue color of the entity when its light flag is set.
PRV Precomputed radiance color (position dependent, see below).

So, the engine seems do not have an ambient light, but the ambient from scene is from model only.

Too bad!!!!

I even set ambient of model to 255,255,255, but It still receive the light

This syntax is right until now, and cause me a big problem

-Go to "File" --> "Map Properties" --> "Sun"
-Set the sun values to 0, including "Azimuth" and "Elevation"
-Set the ambient to the desired value (e.g. 20,20,20)

Now in your level, on a hidden place, make a block with a shaded texture and place a static light above it. It should lit only the hidden block.

Edit: The entities will get their ambient from that block, so you should make it flat shaded and big enough.

After that, you should have a normal ambient without sunlight.
