Hi good people, does anyone has idea how can i fix that uneven lighting on the objects of my map, i tried everything but im a noob at mapping, i guess it has something to do with spec maps and stuff but i really have no idea what to do now

Any help would be truly appreciated 

Some models might not have normal or specular textures.
Sometimes if the models origin is below 0,0,0 when exporting it can look strange in codwaw because the models origin can be in another area.
There is a trap switch model that has the same type of lighting problem because its origin is low in maya.
Try adjusting worldspawn. Put a reflection prob in the area. Remake the model with normal and specular textures. Make sure model is snapped to grid.

Thanks a lot sir its fixed now
