The ThinkingWithPortals Map Showcasing Thread
Well, I've been working on the train-yard area (the final area) in my map. I found a decent skybox texture, and I'm starting to create the final puzzle so the player will escape the facility. This looks a little bland, but here are a few pictures of the area:

Angry Hover Turrets will appear in this area. I still got a lot more stuff to add.

Looking good, but IMO, the skybox seems a little bland. I know they're aren't many out there, but if you could find one with clouds, It would look a little better. Also, does this map have a plot that goes with the train yard?
Plot? I'm not really sure. I was more focused on giving the player an option to escape the facility instead of taking the exit elevator. The train-yard was made to give an interesting outside environment and I could imagine Aperture using trains to receive materials. As for the skybox, I will eventually make a 3D Skybox and I'll try to make some clouds or fog to make things more detailed.
Edit: More pictures, things are looking a bit more detailed. I'm still trying to use the right kind of textures that would fit outside:

Notes
These are screenshots for MultiPortal. Not a lot of detail. Was a fast compile too. However, tell me what you think

[Released] Rust and Dust (Spotlight Map!)
[Released] Multiportal
Looks okay, but it is really hard to tell how the lighting is going to end up, along with some more detail. This also means that the only critique I can give you is that in that last screenthot the laser emitter on the ceiling should probably be centered, not the cube model. That usually looks best and should - in my opinion - be used as often as possible.
I think I'm gonna' like that concept though.

For an early WIP it looks pretty decent already! There are two things I noticed:
* The second screenshot a curved displacement floor with tiles. That looks a bit strange IMO, since I would expect the tiles to come apart a bit instead of making a smooth curve. (The center image in FourthReaper's signature shows a good example.)
I found that this texture works best if you keep the tile parts flat, and raise the dirt parts a tiny bit, as if there are little heaps of dirt on top of the tiled floor. Optionally garnish with some debris props.
* I'm not sure if this is something you're already planning to add, but in the last image, the two light sprites on the button need something for the light to come from, instead of just two floating sprites.

Tell what you think about it! All feedbacks appreciated.
Nah, I didn't know such a video existed. I made the Super-Button explode because the Super-Button makes the panel angle at 30 degrees, I wanted to "Kill" the Super-Button so the player can't trigger the Super-Button anymore because by placing the cube onto the cube button in the inaccessible room, it makes the panel angle at 60 degrees. And 60 degrees is enough to fling to the exit door, while 30 degrees isn't.
