• Water replacer
  • Replaces all map water materials with a single one so it can be replaced in Remix
    • Some non-water materials in maps might get replaced with water. If so, please make a github issue with the map name and screenshot on where its happening.

Installation:

Warning

Ensure you have a clean 64-bit version of Garry's Mod installed with no 32-bit leftovers.

This is a total conversion, do not install this on a Garry's Mod install you care about

1. Subscribe to this addon collection (click Subscribe to all > Add Only)
2. Download the latest release
3. Make a copy of your Garry's Mod installation and call it something like GarrysModRTX. The path should look like this:
   (If you're doing a clean install, open the game once with steam before installing the mod)

• C:\Program Files (x86)\Steam\steamapps\common\GarrysModRTX

4. Open gmrtx64_(ver).zip, extract everything inside to C:\Program Files (x86)\Steam\steamapps\common\GarrysModRTX, overwrite everything.
5. Open the game with the GarrysModRTX launcher
6. Profit.

Incompatible Addons

• (Map) Bro Said He Knew A Spot 💀 (Breaks other shader-skybox maps)

• (Map) gm_northbury (remix cant find a camera)

• (Map) gm_hinamizawa (vertex explosions and untextured draw calls)

• (Addon) MW/WZ Skydive/Parachute + Infil

  • Absolutely destroys vram, what the hell does this addon do

Known issues and stuff that doesn't work:

Vanilla

• Shader skyboxes (gm_flatgrass, gm_construct, etc) (use the hdri skybox addon below as an alternative)

• Some render targets (spawnmenu icons, screenshots, whatever addons that rely on them)

  • Looking into a potential fix

• NPC Eyes (limitation of FF rendering)

• Some particles will not appear (limitation of FF rendering)

• Race conditions with Remix API Lights

  • API Lights will sometimes fail to spawn or spawn infinitely, keep restarting the game until they spawn correctly
  • They can also introduce stability issues and crash the game randomly, at least reported by one user.

• HDR maps (limitation of FF rendering)

• Some materials don't appear (limitation of FF rendering)

• Model replacement for skinned meshes like ragdolls, view modelds, some props, etc.

• 3D Skybox is visible within the main map

• CEF Causes some maps to be rasterized and have vertex explosions. Use the noCEF version if you dont want to deal with these issues.

Addons

• High vram usage with a lot of addons (most likely from ARC9 or TFA precaching textures on map load)
• Tactical RP scopes become invisible when using ADS

Main Settings

Custom World Renderer

Replaces engine world rendering with a chunked mesh renderer to get around brush culling.

• Remix Capture Mode disables engine world rendering under the custom world renderer to get clean captures.

RTX View Frustrum

Modifies render bounds to prevent light and static prop culling around the player camera.

• Regular Entity Bounds controls the distance when static props get culled around the player, higher values means less culling but also less performance. Recommended to leave it at 256

• Standard Light Distance controls the distance when light updaters get culled. Recommended to leave it at 256

• Enviornment Light Distance controls the distance when sun light updaters get culled. Recommended to leave it at 32768 unless you're on a extremely large map

• Add Current Map

  • Adds the current map with an assigned Render Bounds preset. Sets the preset on map load.
