to see existing custom maps in pyrovision, we need to put the file mtp.cfg into your /tf/cfg folder
(add your custom map into the array)
Typical path is:
c:\Program Files (x86)\Steam\steamapps\<your_account>\team fortress 2\tf\cfg
Code:
"VisionFilterShadersMapWhitelist"
{
"arena_badlands.bsp" "1"
"ctf_2fort.bsp" "1"
"cp_badlands.bsp" "1"
"cp_dustbowl.bsp" "1"
"cp_gravelpit.bsp" "1"
"koth_badlands.bsp" "1"
"koth_viaduct.bsp" "1"
"plr_hightower.bsp" "1"
"pl_badwater.bsp" "1"
"pl_goldrush.bsp" "1"
"sd_doomsday.bsp" "1"
"NEW_CUSTOM_MAP.bsp" "1"
}
