For some reason models within my map are changing colour unexpectedly. I use the model in a certain spot in the map and it looks fine, I then copy the model to somewhere else in the map and the materials go all wrong. It looks fine in Radiant but is wrong in game. It's hard to explain but hopefully the image linked below will explain the issue. The image shows the exact some model, copied twice, literally right next to each other but they look completely different. All help is appreciated! Thanks!

That's weird. Did you try not copying them ?

See if this info helps:

Models light is determined by model's origin.

Have tried these fixes that you guys have suggested but they don't seem to have helped unfortunately. I have a feeling that the models are being affected by my world spawn settings as the colour change on the models is the exact same colour that I am using within my world spawn settings. I've got another screenshot here to show the issue better than the other image. This shows that it's not just Custom Models but is also WaW models which are being affected.

Dont use models for floor purposes completely

Hmm, that's what's causing it? Ok, will give it a fiddle about and see what happens, thanks! Strange though coz it's also happening to a pipe model which is going through the ceiling? I also found that putting a weapon clip inside a model causes it.

Even when moving them into the centre of the room, the issue still occurs: http://prntscr.com/azdz64

This is 6 separate models but they are all the same.

Well, that issue doesnt happen with brushes, so just make the floor out of brushes and align textures to be same as the models, lol
