I'm a beginner in mapping Portal 2 maps, I just started one or two days ago, so there's very much, that I don't know.
And sorry for my bad English, I'm from Germany. (Is there a German Portal 2 community? I didn't find one, so I decided to register here instead.)

I uploaded two test maps here: https://rapidshare.com/files/3988339426/chiko.rar
Please download them, to see my problems.

chiko5b is a co-op map. I know it's really simple, but it's playable and it's one of my first trys.
Problem here is the slime water, because it doesn't look like slime water. It works correctly. The player will die, when he falls in. But it doesn't look like slime water, it looks like ... nothing!

chiko6 isn't a real map, just a little test. I tried to install a gel dropper, but it doesn't work. Can't find out what's wrong there, so I would be really happy about some help.

Thanks in advance!

I have already read this, but it doesn't help me.

The level with the paint needs to have paint enabled in order for paint to work. Also your level can't be fullbright or the paint will not show up correctly. To enable paint, go up to map properties and enable it. If you wish to modify the blob count it's best to put it lower than 250, (that's alot of blobs!)

Your poisen water may not work because you tied it to an entity. For example: Do not make the water the thing that hurts you, ( trigger_hurt,) put an invisible brush in the water that hurts you. Hope this helps!
