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.

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..

The error pretty much sums it up. You have bad uvs somehwere on your model. Import debug.wrl and it should show you where those bad uvs are with blue faces.

fixed it.
