Streamline

Ouch, my brain. Finally cracked it after 2 hrs 😅

I didn't realise you could shoot the laser platform floor from the exit room but I solved it by angling the beam so much to the funnel switcher that I could create a portal below the glass room and use the cube in the room to hit the door opener without the funnel taking it away. A solve is still a solve. Playing other Mevious chambers I was not expecting so much white, you are usually channelled down the only woute to solve.

Remember, glass is permeable.

Cool ending setup

This was so much harder than it should have been.

I'm still upvoting because I've enjoyed the challenge, however I have a couple of problems with this map.
First, the blind placement of the cube from below is a bit finnicky, nothing too hard but can be really annoying if messed up and doesn't really feel like the correct solution.
Second, I'm not sure I solved the last step correctly, I did it in the same was as the featured video but it didn't feel right, especially going back to the original platform using the funnel strafe.

Meh.. i make this wayy too hard to myself.

There's an apparent trap in Streamline, where you can wind up on the platform with no funnel to get you off of it, but I discovered that there's a cleverly provided escape!

Look at the thumbnail to see the trap, get yourself into that situation, try to find the escape, and if you can't find it then play the video to see it.

Wow, that last move was so simple in theory but took me a quite a while to see, I think just due to the sheer size of the chamber & the fact that you don't return to the entrance/exit enough to realize what all is visible from there . Well done, thanks for mapping.

I was technically stuck on this chamber for more than a year: every time I came back to Portal 2 I'd give this one a shot, get stuck, and leave. Finally at some point I really thought critically about it, came up with the solution, at felt really good about it. Definitely got me into going through lots community puzzles.
