Tired of the many basic attempts at creating an Overgrown version of the Portal 1 aesthetic? The Flawol Overgrown Portal 1 Pack (or FOP1P, pronounced 'fop-ip') has you covered! 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.

Donuts aren't good for your body, but this map is good for your brain. Actually, it's meant to mess with your head. Look around. Explore. Look behind you. Strange things happen. Unzip the file, put some sprinkles on it and stick it in your maps folder.

The BSP's have a different name, but I came up with this name after the fact. It's a journey through abandoned industrial upwards to BTS. I focused on making stunning aesthetics (or at least I think they should be). Most people know what to do with the files, but if you're not sure, place the BSP files in the games Maps folder.

This is a model of an IMB 5150 for anyone who wants to enforce that 80's theme of old aperture.

Heyho, I made a gel converter for you. The concept of the gel converter is to convert a gel into another gel. For example: Convert bounce gel to portal gel. You may change some settings for your own implementation. This map contains: ? gel converter device ? rotating device ? binary switch for two colors How to install: Just export the .vmf to /../Portal 2/sdk_content/maps and open with the hammer editor.

This is my time buttons for Portal 2. The blue buttons activate the object immediately, but deactivate after a some time after releasing. Green buttons work in reverse, activate the object after a some time after pressing, but deactivate immediately. If you use these buttons in your maps, don't forget to include materials and models in your .bsp file!

(Instances) Extra Elevator Instances

This is my first time uploading a file to thinkingwithportals. If I forgot anything, let me know. You ever look inside the turbine_elevator folder in the instances folder and browse through the elevator vmfs. To find that for the departure elevators, Valve only has the fixed one going up and the destructed one going down? What if you are making an overgrown style map but want your exit elevator to go up? This is where this comes in. Supplied in the zip archive, you will find 2 extra elevator bases. One that is destructed and goes up and one that is fixed and goes down.
