Level Design Several holes in map

Have you tried doing a complete geometry and BSP build? Go in build options and check off lighting, paths and hit build. I've encountered this sort of thing before and that has always fixed it.

Try converting the simple brushes that are near the BSP hole into static meshes, save it in package "myLevel" and replace your BSP brushes with the static mesh equivalents.

Indeed. Changing your brush to a static mesh would work.
But don't do it with complex bsp's.

I had this problem many times during mapping.
And ive learned how to avoid it.

1st remedy:
Make all of your Brushes / Volumes / BSP all to an even number
So, make sure the brushes are not off the grid on your map.

2nd remedy: (and the best way to kill it)
Select the offending brush, and Order it to build last. You can do this by rightclicking the brush, and then Order, and then To Last.

This can sometimes prove annyoing.
IF YOU HAVE a added brush (Add) inside a Subtraction brush "subtract", and you change the order of the Subtraction box, it will not build the Added brush inside that room!
So, you need to then change the order of your added brush to "To Last"

3rd Remedy: (most common but very very ugly)
Block up the BSP hole with more volumes. I do not recommend this.

4th Remedy:
Delete unnecessary brushes and volumes. Or move them around.

Hope that works for you.

yup, bsp is a huge pain in the arse.

Did you try reducing the grid size before placing or snapping ?

Haven't touched the editor for ages so I might be mixing something up.

sometimes moving the brush a littel seems to fix it sometimes. hope it helps u out remaking the brush is also an option!

I just deleted the wall and copied it again and then there wasn't any hole, very wierd indeed

Yeah. I've been chasing down BSP holes in the side of my map for the last few days. I'll kill it, run the map, all is good, come back a day later and it's back. BSP holes are like bad pennies.
