RealityShaders

About

RealityShaders is an HLSL shader overhaul for Project Reality: Battlefield 2. RealityShaders introduces many graphical updates that did not make it into the Refactor 2 Engine.

RealityShaders also includes .fxh files that contain algorithms used in the collection.

Features

• Shader Model 3.0: Shader Model 3.0 allows modders to add more grapical updates into the game.

  • 3D water and terrain
  • High precision shading
  • Linear lighting
  • Procedural effects
  • Soft shadows
  • Sharper texture filtering
  • Steep parallax mapping

• Updated BF2Editor Shaders: The Shader Model 3.0 update allows BF2Editor to support updated dependencies and Large Address Aware.

• Distance-Based Fog: This fogging method eliminates "corner-peeking".

• Half-Lambert Lighting: Valve Software's smoother version of the Lambertian Term used in lighting.

• Logarithmic Depth Buffer: Logarithmic depth buffering eliminates flickering within distant objects.

• Per-Pixel Lighting: Per-pixel lighting allows sharper lighting and smoother fogging.

• Modernized Post-Processing: This shader package includes updated thermal and suppression effects.

• Procedural Sampling: No more visible texture repetition off-map terrain.

• Sharpened Filtering: Support for 16x anisotropic filtering.

• Optional Bicubic Lightmapping: A smoother interpolation method to eliminate blockiness and noticeable seams in baked lighting. Credit to Felix Westin.

Installation

1. Click on the green <> Code drop-down button and select Download ZIP.
2. Unpack the downloaded RealityShaders-main.zip file.
3. Locate your \mods\pr directory in your Project Reality: Battlefield 2 installation.
4. In the \mods\pr directory, create a backup of the shaders_client.zip file. Name the backup something like shaders_client_backup.zip
