.Map :: MoHAA Mapping

how do i know which brush is number 30? there are several brushes there when i do 'find entity/brush'

EDIT:
never mind what i said at the top, i recreated brush 30, and now im only getting: so how do i find this float brush?

there's a sticky topic on Compiling errors, this is what it says:

ERROR: FloatPlane: bad normal

Somehow you've created an invalid brush in your map. At least one face of this brush will be invisible in game. This usually is the result of careless vertex-editing.

SOLUTION: Use the Rogue Plugin to remove bad brushes. (.ace file requires Winrar)

Create a folder named "plugins" in the directory where your mohradiant files are (eg. Mohtools/plugins). Extract the plugins to that new folder and you're set to go. Start Mohradiant and in the menu look for the "Plugins" option next to "LOD terrain".

using the plugin i deleted all evil polys and duplicate planes.
but the problem is still the same as the last screenshot.

and now i dont have anymore floatplane: bad normal or duplicae plane errors while compiling.

Make sure your skybox is sealed (file/pointfile). Is your shaft surrounded by LOD?

just having a guess at the problem my be more simple than you think.

Does radiant allow the map to go below the grid + are the walls in line with the grid squares.

yeah that's what I was thinking when I mentioned the axes-lines in radiant. The compiler always starts by slicing the map along the x- and y-axis. If a brush is flush with one of those axes it could produce errors, but it's unlikely.

I've had the weirdest errors while building maps and it sometimes didn't make any sense at all. Best thing to do is delete and rebuild that room and try different things, like thickening that wall a bit, or rebuilding the room a little different. Just improvise.

i recreated the room somewhere else and now its works just fine
thx for all the help fellas, much appreciated.
