Texture lighting problems

[Kommander_K]

OK I am working on my first map in source, its for TF2. Right now I have this problem that every surface that has the red sides roof texture changes its lighting depending if I am standing in the shade or not ( its bright if I'm in the sun, and dark if I'm in the shade). I can not for the life of me figure out what the problem is.

Help is much appreciated

Cubemaps being messy perhaps? Not sure though... However this seems to be an issue in TF2 altogether. Look at the rocksides in dustbowl and note how they also change as you move around.

i dont think its cube maps, its a non reflective surface

Is it a texture intended for a model perhaps?

Cubemaps cannot presently be built for maps that run in an Orange Box game.

something is worng with cubemaps regardeless so it might be related still...

As of this morning's SDK update, cubemaps can be built.

The OP's problem sounds like he's using a vertexlitgeneric texture (i.e. one from a model) on a lightmapped surface.
