### 🎨 Texture Setup & Pipeline

1. **Blender:** Open the provided `.blend` file. All UDIM texture sets are pre-linked to Shader Nodes. Ensure "UDIM Tiles" mode is selected in the Image Texture nodes if reconnecting manually.

2. **Unreal Engine 5:** Import the `.fbx` from `02_GameReady_LowPoly`. Drag and drop the maps from `UDIM_Textures/Unreal_Engine_Set`. Ensure Occlusion, Roughness, and Metallic maps are unpacked correctly or assigned to appropriate material channels.
