Fun map. I'm not entirely certain if I did one of the parts as intended though In the chamber with the funnel, light bridge and propulsion gel I got the box for the button by putting a light bridge under it and letting it bounce off in the right direction so I could catch it. Was there a different way for this?
You included your BSP in the "sdk_content" directory, not your VMF. Strangely, I am able to extract this BSP just fine.
I am able to extract the BSP now without a CRC error.
Yep, I guess the problem was having 2 .bsp:s with same name. I though I took .vmf but I copied .bsp by accident :S (Why there is .bsp file in sdk_content folder anyway...)
Had a problem in the last room.
I honestly thought I had to hit the button to be able to use the light bridge. Because when I was just standing on the floor I couldn't place a portal at the end of the bridge. So, I figured if you hit the button it would remove the black squares on the side so that I could place a portal.
After I did that and it still didn't work I gave up & came back on the forums here to see if anyone else had this problem.
No one did so I watched the dude's video of it & saw I could only place the portal in the air? what is the point of that...
Uhh, there are white tiles in the ceiling.
Quick and witty: a series of small fun chambers likely to fly by, thankfully because they're to the point instead of wasting time in preliminaries. Walls could be more tridimensional.
