Can you combine the subtract and add brushes together?

I would like the to combine these two brushes with the result being a brush that has the empty space created by the red brush merged with the blue brush. In other-words, I want the hole the red brush creates with the vertices of it auto generated onto the blue brush at the edge intersects…I’ve seen other tools do this. Is this possible? For example, in Blender I would accomplish this with a boolean modifier.

As far as I can tell this is not possible in Unreal Engine right now. In Blender you would add a “boolean” modifier to make this work.

Also UDK allows for brush booleans.
In this case you could split the vertical edges in geometry mode and model the recess manually.

All these functions (like Deintersection) are still available in c++.
You can develop tools or expose them easily with buttons. Just did it yesterday.

Another way is to use console commands like “BRUSH FROM DEINTERSECTION” for example.

It’s hidden but sill here :wink:
