Left 4 Dead 2 - RTX Remix Compatibility Mod

This client modification is specifically made for nvidia's rtx-remix.
How does a shader based game work with remix? By manually reimplementing fixed function rendering :)

WIP & Please Note:
RTX Remix was never intented to support this game so expect stuff to be broken.
This is not trying to be a remaster. It simply makes the game compatible with RTX Remix.

Please keep that in mind.

🔹Most things are rendered using the fixed-function pipeline🔹

Usage / Installation

• Download the latest release and follow instructions found there.
• Start the game by executing l4d2-rtx-launcher.exe (start as admin if game is installed under Program Files)
• The window title should change to Left 4 Dead 2 - RTX - followed by the GitHub commit number if successful

🟦 Info:

• See the Wiki for in-depth guides on features that come with the compatibility mod 🍓
• Current releases ship with a custom build of the remix-dxvk runtime which includes necessary changes for L4D2 (bin/.trex/d3d9.dll)

🟩 Remixing:

• Press F5 to open the in-game gui to tweak compatibility mod related settings or to edit MapSettings

• Infected will be really colorful when viewed in the toolkit. That is the colormap the infected shader is using. DO NOT touch anything on infected meshes BESIDES the normal map!

• Water surfaces have two layers. Make the top one translucent (and animate the normalmap with a spritesheet if you want). The lower layer can be used to color the water and make it interact with the flashlight. Remove the albedo map and set a albedo color + opacity if you want. Reduce the roughness and increase the metallic amount to your liking.

  Then, modify the alpha blending as follows:

  • Use Legacy Alpha
  • Blend Enabled
  • Alpha Test Type :: LessOrEqual
