How to use this ORM Packer?

Creating optimized textures for game engines like Unreal Engine 5 requires "Channel Packing". This technique combines three different grayscale images into the Red, Green, and Blue channels of a single texture file.

1. Upload Inputs

Drag and drop your AO, Roughness, and Metallic maps into the corresponding slots.

2. Adjust Settings

Choose your output resolution (e.g., 2K or 4K) to match your project needs.

3. Download

Get your packed texture instantly. No server uploads, 100% private.

Why use Channel Packing?

  • Save VRAM: Using one texture instead of three reduces memory usage by 66%.
  • Reduce Draw Calls: Fewer texture lookups mean better FPS for your game.
  • Standard Workflow: Unreal Engine expects ORM (Occlusion, Roughness, Metallic) maps by default.
