### 2. Software & Engine Integration Guide

#### A. Blender Setup

1. Open the `.blend` file inside the `Blender_Scene/` folder.

2. Materials and lighting are pre-linked and ready for immediate rendering in Cycles or Eevee.

3. If texture paths are broken after moving files, go to `File > External Data > Find Missing Files` and point to the `Textures/` directory.

#### B. Unreal Engine 5 Setup

1. Import the `.fbx` mesh from the `LowPoly_Mesh/` folder into your UE5 content browser.

2. Ensure **Import Normals** is set to "Import Normals and Tangents".

3. Use the dedicated textures from `Textures/UDIM_UE5_Optimized/`.

4. Create a Material in UE5 and plug in the packed channels (Red = Ambient Occlusion, Green = Roughness, Blue = Metallic).

### 3. UDIM Texture Information

This asset utilizes industry-standard **UDIMs** to ensure maximum Texel Density across all gun components (receiver, barrel, scope, stock).

* **Blender / Marmoset Set:** Contains separate BaseColor, Metallic, Roughness, Normal (OpenGL & DirectX), and AO maps.

* **UE5 Set:** Pre-packed maps specifically calibrated for Unreal Engine’s material editor pipeline.

### 4. Tutorial Instructions (If Bundle Purchased)

* **Format:** High-definition, silent screen-recorded workflow with visible keyboard shortcuts and mouse clicks on screen.

* **Recommended Learning Flow:** Follow sequentially through the folders: Modeling → Retopology → UV Unwrapping → Baking → Texturing → Rendering.
