understanding original valve maps lighting

[Gnomesenpai]

Hey guys, so i'm currently tweaking the MvM Ghost Town map by moving the giant bot spawnpoints from the sides to the middle, on compiling the map and running it i've noticed that even on the HDR -slow compile the lighting is just off compared to the original. Hw could I solve this? I know next to nothing for Hammer so any guides to "copy" the original lighting would help as i only want to move 2 spawnpoints!

I suspect the real problem is that the decompile process messed something up. The light_environment seems to not be working at all.

Is their anything i could do about this? another method to de-compile? or am i stuck as is if i dont want to re-create my own light_enviroment?

Try decompiling it again, or downloading it from https://tf2maps.net/threads/valve-maps-decompiled.5952/ if you didn't get it from there originally
I'm not 100% sure on the 'broken light_environment' though, because you can see at the very edge of the skybox that there is something being lit properly

Decompiled maps often have broken areaportals and and occluders. Improperly constructed areaportals in particular can cause leaks, which will force VRAD to do simple, sloppy lighting that doesn't look good. Either fix the areaportal leaks or delete the areaportals.

paste -noskyboxrecurse into VRAD commands before $gamedir $path\$file and this will be fixed
