Portal 2 cubemaps

How to build cubemaps in portal 2? I have placed cubemaps near metal surfaces, and run buildcubemaps -command in-game. They build fine, but still, no reflections appears...

You may need to restart Portal 2. Also, does your map have lighting?

of course it have lighting. I will try restarting.
EDIT: IT DOESNT WORK

Are your game settings low enough that reflections are not enabled?

Post an in-game screenshot please.

I don't think alot of Portal 2 textures use cubemaps from what I've seen. Even without lighting in a map, many textures will still use some sort of default reflection. My current map looks exactly the same with and without cubemaps. It's only if I apply certain textures that it's noticeable.

Metal walls uses reflections. My settings are medium-low. If I try higher settings, my game crashes, when I run map.

Reflections are only enabled for textures (as far as I can tell) when the Shader settings are on high.

Have a nice day,

Maybe you settings are too low to render reflections. This is the exact same situation someone else had, so I'm guessing that's the case.

Surprise: You need a computer that is newer than 6 years old to see modern effects such as reflections.
