Do cubemaps matter?
They are used on every reflective surface, from metal to the gel splatter to the cubes
By the way, does this look like it was made by somebody who has no idea how to use the source engine?

Yes because we care about your 1.5 very much. >.>

Guess what msleeper, I do know how to use the source engine, now can you please stop bashing me whenever I ask a question? I've added in cubemaps into my map and nothing changed at all. I ran buildcubemaps and everything so I figured they weren't needed.By the way, does this look like it was made by somebody who has no idea how to use the source engine?
Notice how the metal walls are not giving off any reflections? Sometimes too you need to reset portal or the map for it to appear properly.
after building the cubemaps, make sure you execute the "reload" command in the console for the cubemaps to be applied.
make sure you check out the VDC:

Oh and BTW i've always wondered if it is a model or just brushwork to make the frames for glass in Portal 2. Anyone?
It's a model. (check out the zoo_mechanics.vmf for the model name)
You have to put in the console:
buildcubemaps
mat_reloadtextures
mat_reloadallmaterials
I discovered it by myself messing around with the console.

Truth. Also, faith plates. Horrendous without cubemaps.
