TLDR:
you gotta make a cubemap vtf and apply it to your $ENVMAP material param
you can use a premade vtf from an env_cubemap extracted from a bsp OR make one yourself with the cubemap screenshot tool found here:

point south (hammer grid south) take a screenshot with that,
ur cubemap screenshots are here : (all my paths are prob different from your paths)
T:\STEAM\steamapps\common\GarrysMod\garrysmod\data\cubemaps

convert those to targas and put em HERE :
C:\Program Files (x86)\Steam\steamapps\common\Half-Life 2\ep2\materialsrc\test (or wherever the TEST folder isnt required)
gmod: T:\STEAM\steamapps\common\GarrysMod\garrysmod\materialsrc\test

create the txt file and apply the file changes as seen in the video
open
C:\Program Files (x86)\Steam\steamapps\common\Half-Life 2\bin
or for gmod
T:\STEAM\steamapps\common\GarrysMod\bin
