Build cubemaps for a Garry's Mod map in both Low Dynamic Range (LDR) and High Dynamic Range (HDR)

build-cubemaps.md

This fixes issues with objects and weapons appearing very shiny in the map.

• You must have a copy of the map in your Garry's Mod folder
• If you wish to fix a workshop map, you must first extract the map file

---

Before running the steps below, enable HDR:
Options -> Video -> Advanced -> "High Dynamic Range" -> Full

Open the map in singleplayer and enter the following console commands

1. sv_cheats 1
2. mat_hdr_level 2 (to go to HDR)
   • The map should reload. If it doesn't, enter the command restart
3. building_cubemaps 1
4. buildcubemaps
5. mat_hdr_level 0 (to go to LDR)
   • The map should reload. If it doesn't, enter the command restart
6. buildcubemaps
7. mat_hdr_level 2 (to go back to HDR)

thx!
