When using original office lights, I always hated the fact that there was almost no difference between original skins, so I made new ones! (Everything is shown in the image) Skin 0 - Warm light Skin 1 - Warm light (With gray metal) Skin 2- Cold light Skin 3 - Cold light (With gray metal) Skin 4- Neutral light Skin 5 - Neutral light (With gray metal) Skin 6 - Off light Skin 7 - Off light (With gray metal) Would be nice, if credited as "AbbieInSpace" Feel free to edit textures, how ever you want, and let me know if there are any problems!

NOTICE SO VALVE'S LAWYERS DON'T SKIN ME ALIVE: I will NOT be giving any downloads to the leaked builds or any help on getting the betas working. Figure it out yourself. A simple little playground map I made for the leaked "Core Hub" build of Portal 2. It may or may not work on other beta builds or the retail version of the game. Has custom materials and (non-working) sounds (I'm too lazy to get them to actually work). How to install this: Simply drag and drop the included folders into the "portal2" folder.

The walkway_gate_b model, but with brushwork to make it look like walkway_gate_a. Useful for little details like the stripes falling off. Place the .vmf in the bin/Prefabs folder of Portal 2

This pack aims to resolve this problem by faithfully remixing all the texture set of Portal 1 in the Portal 2 Overgrown style. This pack features: 27 textures, composing of every possible variant for the Concrete, Metal and Plastic texture sets all lovingly damaged faithful to their looks - and more! Blend Materials for every possible floor variation! With both of Portal 2's dirt and moss blends being used! Every P1 Test Chamber Model retextured and adapted with a remake of P2's Craquelure texture, creating an authentic Valve-style look to the models.
