Need some unusual help.

[Gird3r]

For those who did not know, It is possible to create Portal 2 maps using the Alien Swarm SDK (Using the Hammer editor) and some finetuning.

I got 2 problems.

1. I am unable to create any further Blocks/brushed/whatever the name is. As soon as I click Create Object it dissapears into thin air.
2. I was actually able to load my ownmade Portal 2 map into the game. There's just an slight problem: The screen looks like an Bloomy screen being filled with one color depending on where I am looking. Like if someone took the handle on Bloom and pushed it way past the limits. It just looks extremly horrible (I had this problem aswell when I was attempting to map for TF2, but then it was with an official SDK for TF2).

As for the project: I'm planning on making an reaction test course, Where speed (repulsion gel ftw) and some ok memory is the thing you need. Not so much puzzle solving. And also, because I miss the map from the Portal 2 demo where Chell jumped over an gap while there was spike blocks chasing after her smashing. Which I found to be extremly awesome.

I'm thankfull if you could help me solve my problems.
