AC Odyssey visual optimization package

Balance auto-exposure with tone mapping, adjust shaders and add slight brightness sharpening.

AC Odyssey visual optimization package

✨ ** Take your "Assassin's Creed: Odyssey" visual experience to the next level! ** ✨

🎨Module Introduction

Although Odyssey is a beautifully lit game, it (and other games that use similar lighting systems, such as Mass Effect: Andromeda, Dragon Age: Inquisition, and Origins) sometimes push too hard with **auto-exposure** - especially when switching from bright to dark environments.

This mod aims to balance the visuals by:

• **Dynamic Tone Mapping**: Reduce areas that are too dark and too bright.
• **Color Correction**: Reduces slight yellow tint.
• **Brightness Sharpening**: Add a touch of clarity to the picture.

Just look at the screenshots and in-game settings to see the changes!

⚙️ Core functions

This mod includes a custom shader `upscale.hlsl` for full screen adjustments including sharpening and color modification.

Additionally, several fine-tunings have been made via **3Dmigoto**:

• **Softening God's Light** 🌅
• **Remove the lens splash effect during diving** 💧
• **Slight tone curve adjustment via custom shader `curve.hlsl`** 📈

📝 Update log (v1.1 - October 14, 2024)

• Further tweaks to tone mapping, adding **Contrast and Saturation**.
• New shader functions: **Remove specific special effects, reduce vignetting, and reduce fog density** (see the shader list below for details).

📥 Installation Guide

**Basic installation (recommended)**

• Copy all files in the compressed package to the **game installation directory** of "Assassin's Creed: Odyssey" (that is, the folder containing `ACOdyssey.exe`).

**Optional installation (use official 3Dmigoto)**

If you don't want to use unverified DLL files, you can follow these steps:

• Download **3Dmigoto 1.3.16.0 (64-bit)** from GitHub.
• Place `d3d11.dll` and `d3dcompiler_46.dll` into the game installation directory.
• Copy the `ShaderCache`, `ShaderFixes` folders and `d3dx.ini` files in the compressed package of this module to the same directory.

**IMPORTANT NOTE**:

• If using `d3dx.ini` from the GitHub package, make sure to change `hunting=1` on line 248 to `hunting=0` (default is debug mode).
• Also, on line 19 add:

```

include = ShaderFixes\upscale.ini

include = ShaderFixes\curve.ini

```

✅ Verify installation

After running the game, the `ShaderFixes` folder will gradually generate `.bin` files (compiled by 3Dmigoto) according to the scene and level. If you see the following files, the installation is successful:

• `3f8c8e5bf6060d95-ps_replace.bin`
• `767d3b2f46009ef1-ps_replace.bin`
• `8b7c3744824a6cae-ps_replace.bin`
• `a78acd74fdfee1fa-ps.bin`
• `ad6b6e79d4880c69-ps.bin`
• `curve.hlsl`
• `upscale.hlsl`

🔧 Advanced Customization

Like to toss? You can adjust it yourself!

**Disable specific features**:

• To disable the curve shader, change `include = ShaderFixes\curve.ini` on line 20 to `;include = ShaderFixes\curve.ini` in `d3dx.ini`.
• To disable a specific tweak (e.g. Soften God Light), simply delete the corresponding `.txt` file (e.g. `3F8C8E5BF6060D95-PS.txt`) from the `ShaderFixes` folder, delete the corresponding `.bin` file if compiled, and restart the game.
