Would you be able to provide the command line arguments you're using and also a link to download the boot_camp map?

here's the maps and gfx folders, in the maps folder have a script that I made to mass convert the maps, I think it will be more easy to see on what maps it doesn't work.

And the command line is this:
bsp2obj -g hl1 -o boot_camp -m C:/Users/LUÍS/Desktop/valve/maps/boot_camp.bsp -c C:/Users/LUÍS/Desktop/valve/gfx/palette.lmp
