This is supposed to be fix when I convert to mesh, and weld verteces to low number. When I compile my scenerio and collision bsp, I have no errors except for nearly coplanars, which can be compiled. When I do the lightmaps, tool lightmaps levels\two\two two 0 0.9, I get this message:

C:\Program Files\Microsoft Games\Halo Custom Edition>tool lightmaps levels\two\t
wo two 0 0.9
Couldn't read map file './toolbeta.map'
i'm going to render debug lightmaps for two of levels\two\two, and i'll stop whe
n red+blue+green = 0.900000.
Hit control-c now if this isn't right.
WARNING: 1 clusters in structure_bsp levels\two\two have no background sound or
sound environment.
start levels\two\two
radiosity error: degenerate triangle [or triangle with bad uvs] (see blue in err
or geometry)

This happened to me on my last forerunner structure. I never got that to work either. I'm frustrated..

I told you how to fix this im sure. Read over our chat log again.
Import Debug.wrl and re uvw the blue parts.
