tool ERROR couldn't update edge(red)

[genwhite]

i made a map with an underground bunker but when i try to compile in tool, it says,

C:\Program Files\Microsoft Games\Halo Custom Edition>tool structure levels\splinter splinter
Couldn't read map file './toolbeta.map'
building intermediate geometry...
### WARNING found #8 degenerate triangles.
building collision geometry...
### ERROR couldn't update edge #39 (red).
### ERROR couldn't update edge #33 (red).
### ERROR failed to build collision geometry.
### ERROR failed to import collision bsp.

C:\Program Files\Microsoft Games\Halo Custom Edition>

and when i checked my map, the corners it said had the error were two of the corners in the back of the bunker. I don't know what i have to do to fix this error, but help would be appreciated. Thanks!

A) It may not be sealed
B) It may have overlapping edges (aka, a degenerate triangle that it doesn't ant to mention)
or
C) It may have a triangle that goes like this:

|/|
__/| |
/"" |
"""""
Which is really fudged up

To get it all fixed:
Start 3ds max (or gmax, but idk, does gmax import wrls?) and import splinter.wrl (found in your halo ce directory)
when it asks what to do with the import:
Deselect everything EXCEPT import geometry or whatever.
You will now have colored lines on your two bade edges.

Oh, yeah, and you have triangles with 0 area, which is probably what is causing the problem.

i imported it, but the lines are in the middle of the skybox, not attached to any thing in particular.
