UDK CSG subtract problem

REK-3

hey guys

I have problem with CSG subtract option.
When i press the CSG add button its working properly, but when i try the subtract, nothing happens I have this problem since i started using UDK.

Is there any solution for this problem?

What type of level are you working in? additive or subtractive? Subtract will only work if you are working in a subtractive level or are trying to subtract from an additive brush.

also if you have a CSG subtract brush that is the same size of a CSG add brush, it will either do nothing, or completely disappear. a friend of mine had a level that i went through to clean up, and 1 area had about 8 CSG add/subtract brushes on top of 1 another, but the add still showed over them all.

Sean VanGorder

Yeah, and you can change the order the brushes are calculated in by right clicking them and going to "Order".

This may sound stupid, but how i can change the geometry style in the newest UDK build?

I tested subtractive and additive mode in unreal 3 editor and this time it does not show even add brush in additive mode.

as far as i know in the newer versions of udk.. its only additive mode now. just using ctrl+A will create an additive brush.. and ctrl+s makes a subtractive. if you want to change from 1 to another.. right click on it, go to CSG and you can choose which to use there..

hope that helps

Okey, i find the way how to change mode now, but still nothing happens.
I think it doesnt work because i am using ati radeon hd 5700. I installed udk with my laptop with has nvidia driver, and the subtract brush worked. I had driver issue also with source sdk. So i expected that there is same kind of issue in udk.
