Features

• ToPBR: Automatically converts Source Engine materials to PBR at runtime
• Hardware Skinning (For Half-Life 2 RTX Assets)
• Remix API Support (including Lua bindings for addon creation)
• Prepared PBR assets in GMA addons: prepare DDS replacements before renderer startup and reuse them on later launches (Windows x64).
• Win64 legacy texture-hash replacement provider for Advanced Material Editor (protocol and safety notes)

Installation

• Switch to the x86-64 branch of Garry's Mod on Steam

• Ensure you've ran the vanilla game at least once, especially if you switched branches.

• Download RTXLauncher (Use the newer nightly if available).

• Windows

  • Run the launcher (as an Administrator)

• Linux

  • Ensure Steam Play is forced for Garry's Mod with either Proton Experimental or another recent Proton build.
  • Run GModPatchTool
  • Make sure it's marked as executable chmod +x ./RTXLauncher.Avalonia.Linux, and run it.

• Select the Release Channel (Stable or Nightly)

• Select Start Quick Install on the main screen and follow the prompts when asked.

• Once it's finished, press Launch Game at the bottom of the launcher.

Multiplayer

Multiplayer works best when the server/host has this addon and the cvar sv_allowcslua 1 set.

You can join servers without the addon but you will experience visual issues.
