The render looked flat for some reason, the only way i fixed it was bu exported all my stuff as obj and reimporting it to new max file. Merging it didn't work.
Specular was turned off.
There was no specular map or lighting in the scene.
The problem wasn't looking at only diffuse, it was looking at normals with diffuse on.
I am still not sure what caused it, but now I fixed it by exporting then reimporting the static meshes on to a few max file.
I have fixed the problem now but thank you guys for trying to help.
