Don't laugh your ass off

[Lodev]

Don't laugh your ass off if you think this is a newbie question, but, where the hell is DEINTERSECTING used for?

I use intersecting a LOT, but when I deintersect, the brush just becomes one small dot.

So please tell me, where's deintersecting used for?

Thanks a lot

This is kinda hard to explain, so I may need someone elses viewpoint so you can understand it.

However it is a very, very impotant tool.

Lets say you have a room. You don't want the room to be square though. So you decide that you will make a cylinder and make it so only half cylinder is in the room on one side of the box.

After everything is lined up you hit deintersect, this erases that half of a cylinder that is outside the box. You are left with the half that is inside the box. Now you add the brush to your world.

If you had intersected, instead of deintersected, you would have been left with half a cylinder OUTSIDE the box. Instead of Inside.

Make sense?

Good explination!

In general:

Deintersect cuts everthing away that is outside of the world and can't be seen later.

Intersect cuts away everything that doesn't directly touch the biulding brush.

Thanks a lot! Now I finally understand it. Once I saw it explained in a tutorial, but it wasn't half as clear of your answers, so I didn't understand it.

Now I've got another question, really difficult to explain, but I'll try anyway:

If I have substracted for example a cave, and used a lot of brushes for it, and want to make it one brush.

If I intersect the cave with a cube brush around it, not the cave but the world around the cave, inside the cube of the brush I use, becomes the new brush. So I've got to substract the new brush somewhere else, and then intersect that thing again. After that I get the cave in one brush. But this process is kinda complicated and the result has some errors in it (for example small strokes of 1 unit thick) most of the time.

Does DEintersecting will work for this?

I don't know. IMO intersecting should do it.

Just try it and you'll see the result.

[Lodev]

sorry, I really don't know what IMO intersecting is.

Could you please tell me what's the difference between intersecting and IMO intersecting?

Thanks a lot

ROFLAMO (rolling on floor laughing my ass off)!!!

IMO means "in my opinion"
Perhaps I should have written AFAIK (as far as I know).

hahahahahahahaha LMAO

sorry.........hahahah...... I shouldn't laugh. No offense, but........hahahahahahaha.................

Hey hybrid. You aren't going to be able to intersect a whole cave and make it one brush. It's just too big (hehe, that's what she said). That's why you are getting those errors, like one unlit piece. Intersecting to make one brush is usually only used for things like pillars, supports, lamps, and other small stuff that isn't too complex, but you want to use a lot in your level. For your cave, it should be fine just to leave it separate brushes. You may want to make all the adds semisolid though to speed up the frame rate. Hope this helps. Good luck.
