Hello,
I’ve started my first map and i started this topic so if i get problems i can ask help here. I tried to make my first map like a year ago, but i gave it up soon.
Than i started making a map for Jedi Academy, which is much easier, but i havent finished that neither. Now i want to finish this map. I use GTK Radiant 1.5. At the moment i have few rooms. And im testing doors, windows and water. Im not testing with devmap and thing like that, but i replaced one PK3 's files with my own ones. It works i think.
And here is my first question:
I made place where evryone when can get, but i dont want them to get there…so how can i do and invisible block for them. I saw it on 1944 Huertgen. First i tought its the caulk, but from Marko’s tutorial i knwo i tought wrong. So how can i do it? Thanks
And here is my first problem:
I last tested before i put in a water, door and window and an explosion place.
It worked than,b ut now it writes out this: SV_SetBrushModel: NULL
I tried removing some new items and im still trying, but not working. . 
Thanks for this too
