# Nahida Unity Reference Snapshot

This directory stores the Unity-side raw reference files that describe how the original Nahida sample is assembled.

Why it lives under `docs/reference/` instead of `project/Assets/`:
- The engine asset pipeline imports `.mat` as engine-native materials.
- The engine asset pipeline imports `.shader` as engine-native shaders.
- These files are Unity formats, not engine-native formats.
- Keeping them out of `project/Assets` avoids false imports and noisy asset errors.

What is kept here:
- Unity materials
- Unity shader and HLSL files
- Unity runtime helper scripts
- Unity sample scene
- Unity URP settings assets

The engine-native migration target remains:
- `project/Assets/Characters/Nahida/`

Use this folder as semantic reference only while rebuilding the runtime path inside XCEngine.
