After I made my map in gmax and went through the steps with the command prompt. My map won't show up in Sapien. When I make the lightmaps in tool I get this message:

C:\Program Files\Microsoft Games\Halo Custom Edition>tool lightmaps levels\snipe
rwars\sniperwars sniperwars 0 0.9
Couldn't read map file './toolbeta.map'
i'm going to render debug lightmaps for sniperwars of levels\sniperwars\sniperwa
rs, and i'll stop when red+blue+green = 0.900000.
Hit control-c now if this isn't right.

The part I highlighted is what's telling me is wrong but I don't know what it means.

It's something to do with Radiosity

I got that part do you know what it has to do with radiosity like what I need to do for it to work.
