pl_borneo is repacked, so you might need to 'derepack' it first. You can do that using
bsp_repack -nocompress maps/pl_borneo.bsp maps/pl_borneo2.bsp in the game console.
I was able to decompile it and open it in Hammer regardless, though, oddly. BSPsource gave me errors but still produced a 12MB VMF. I'll fish out the details for you. it's easier if I take them from the VMF and paste them in.
Code:
entity
{
"id" "630340"
"origin" "-1300 -4912 240"
"SunSpreadAngle" "7"
"pitch" "-55"
"angles" "0 30 0"
"_lightscaleHDR" "1"
"_lightHDR" "-1 -1 -1 1"
"_light" "150 169 199 800"
"_AmbientScaleHDR" "1"
"_ambientHDR" "-1 -1 -1 1"
"_ambient" "150 169 199 800"
"classname" "light_environment"
}
{
"id" "630338"
"origin" "-1256 -4912 240"
"use_angles" "1"
"spawnflags" "0"
"mindxlevel" "0"
"maxdxlevel" "0"
"fogstart" "0"
"fogmaxdensity" ".42"
"foglerptime" "0"
"fogend" "5500"
"fogenable" "1"
"fogdir" "1 0 0"
"fogcolor2" "165 183 188"
"fogcolor" "165 183 188"
"fogblend" "1"
"farz" "4400"
"angles" "0 356 0"
"classname" "env_fog_controller"
}
{
"id" "1257346"
"origin" "4614 932.75 1396"
"scale" "16"
"fogstart" "0"
"fogmaxdensity" ".53"
"fogend" "5500"
"fogenable" "1"
"fogdir" "1 0 0"
"fogcolor2" "140 164 170"
"fogcolor" "140 164 170"
"fogblend" "1"
"angles" "0 0 0"
"classname" "sky_camera"
}
Also no disrespect to the map author(s) meant by decompiling the map.
EDIT: pl_borneo has become one of my favourite maps. Great layout, nice, friendly detailing.
