Symmetrizing BSP

[jak_carver]

Hi guys, I searched the forum for this but couldn't find anything, sorry if this has been addressed before.

Let's say you're building a symmetrical level with BSP brushes, you wouldn't want to waste time creating identical halves twice, so how can you symmetrize (mirror) a selection of BSP brushes?

Looked for a symmetry or mirror tool in Unreal Editor but came up empty.

You could highlight the BSP you want to imitate, then left click to the polygons property, and press "To brush". I don't know if this is what you wanted, but just in case you find it useful.

Thanks Kasigawa for the info.

What you're describing is a great feature when working with BSP builder brushes, but not quite related to what I was asking. However I figured it out just a moment ago, what I needed.

I found that I could mirror BSP addition and subtraction brushes easily by doing the following:

-marquee select (ctrl+alt) from an orthographic view the add/sub BSP brushes you want to mirror (top view works very good for this)

-duplicate by using (ctrl+w)

-right click menu>Transform>Mirror Y/X/Z Axis

The above process will create a duplicate (i.e. half of an office building floor) and flip it so the you have two halves. This would be useful for example in a level that takes place in an office building with an east and west wing that are symmetrical; it would be a waste of time to create the east wing and then the west wing. Instead, by using symmetry (mirror), you could focus on creating the east wing first, then simply duplicating it and mirroring in the Y axis from the top view and you will have an instant "west wing" of your office building, saving time and effort. I'm using this to prototype as fast as possible. Hope someone else in similar situation find this info useful.
