After searching the forums I found this awesome instance made by Lp which I instantly added to my map and it workes. Changed the wall and floor textures and... yeah then I noticed some purple textures on the metallwall048b texture to the right of the sign and the metallift below the room which probably indicate some errors: Screenshot

Can anyone reproduce this issue or even suggest a workaround?

Those aren't missing textures, they are missing reflections.

Just build the cubemaps and it should go away.

Did you modify the map and compile again while you had Portal2 running on background AND with that map running? because that lack of reflections on the textures uses to appear when you do so... remember always to compile when an ealier version of the map is not currently being run.

Oh ok - I thought it only gets loaded to RAM so I can compile while running and just hit reload into the console, but this works now. Thanks to you both.
