Buildcubemaps Crashes Game
I just tried it. (Remove map from portal2/maps, recompile to portal2_dlc1/maps, build cube maps).
My game also still crashes after generating the cube maps, but they do show up the next time the map is loaded, so luckily the crash happens after saving the cube maps to disk.

Portal 1 maps: Try Anything Twice | Manic Mechanic
Have moved to dlc folder, and removed every trace of it in the original. Still my water and glass tubes look shithouse.

I wonder if building cubemaps through another game/engine will work?
Try launching the map in alien swarm.
Since I still can't understand why the above described method of changing the path doesn't work for others, I tried to search for reasons and think I finally found a probable reason.
If I'm not mistaken the workaround only works if you either copy the full path from the explorer or 'browse' from the options menue (Build Programs) to the portal2_dlc1maps folder.
Seems as if copy/pasting this line: $SteamUserDirportal 2portal2_dlc1maps alone doesn't work.
Maybe Hammer must be allowed to convert the full path to: $SteamUserDirportal 2portal2_dlc1maps internally. No idea why!
You guys might try it like that...
Don't put the map in the portal2_dlc1 folder, instead, put it in the update folder, from now on, this is where you put your maps to build cubemaps, and put vpks in your new addons folder?
Proof?

If anyone looks here like I did...
I had the error too but I then saved the VMF file to the portal2_dlc1maps folder and ran it from there. I was then able to run buildcubemaps without the error.
I recommend all you guys out there for testing your cubemaps: use the Half-Life 2 cubemap weapon. It's not included in Portal 2, but you can do this by yourself.

Explaination is in the readme.txt
Oh and the portal_dlc method works perfect.
You also can see that you have to put your map there, because if you build cubemaps and Portal 2 is done, an error will appear in the console and the game tries to get your map from the DLCmaps folder.
