I made a door and tried it out, it was fuzzy both sides and there was no hole in the wall to walk through the door.
1. How do make a hole in the wall for a door?
2. Does making the hole and fitting the door stop it being fuzzy?
I found out how to do it, but when I HIGHLGHT it and click the CSG SUBTRACT button and then BACKSPACE it, it deletes the whole wall instead.
Woah! No, No, No No! Never use CSG subtract unless you are a complete fool. I don't think you're a fool. There is no simple way of making a hole in a room. You just gotta make brushes around the adges of you're hole.
This is what the tutorial said to do:
9: Adding a room 9.1 Setting up for a hole Single room maps don’t exist. Let’s keep it that way. There are two ways to make a hole in your wall for a door to fit. But, first, we need a room to connect to. Make another room, and make sure that at least 1 pair of walls are facing each other. Now, for the different methods: 9.1.1 CSG subtract If you want to make 500 doors in a map, and you want them quickly, use this. Basically, to make a hole, you make a brush the size of the door hole, and put it in the spot of your wall where you want your hole. Now, click the CSG subtract button. It will look like 9 small boxes, with the center solid, and the rest dashed lines. It will be near the tool bar. After you click that button, delete the brush by clicking BACKSPACE. And now, you have a hole in your wall.
CSG subtract is a tool like any other. Using it doesn't make one a fool, but a fool might use it without knowing what it does and what it doesn't do. You can certainly cause troubles for your map with carelessly using it, but cutting a rectangular hole in a simple wall won't spoil any map.
Still, I don't use it, because I like the absolute control the clipper tool grants.
I just built around the door, which took me a couple of hours to fiqure out lol.
Learn the clipper-tool. It's better than making a hole your way, and easier. then learn csg subtract. It can be useful. You don't have to use it, but it might be good knowing that it exists.
