What is a Mask Map Generator?

A mask map generator is an online tool that combines multiple grayscale PBR texture maps (Ambient Occlusion, Roughness, Metallic) into a single channel-packed texture. This process is essential for optimizing texture memory in modern game engines like Unity HDRP, Unity URP, and Unreal Engine.

Our free online mask map generator eliminates the need for Adobe Photoshop or Substance Designer, allowing game developers and 3D artists to create professional ORM textures (Occlusion-Roughness-Metallic) and Unity mask maps directly in their browser.

Unity HDRP Mask Map Generation

Unity HDRP (High Definition Render Pipeline) requires specific mask map formats. Our Unity HDRP mask map generator automatically packs:

• Red Channel: Metallic map
• Alpha Channel: Smoothness (inverted roughness)

The tool includes automatic roughness to smoothness conversion specifically for Unity workflows, saving you hours of manual texture editing.

Unity URP Texture Packing

For Unity URP (Universal Render Pipeline), our mask map generator creates optimized textures with:

• Red: Metallic
• Green: Ambient Occlusion
• Alpha: Smoothness

Unreal Engine ORM Texture Generation

Unreal Engine uses ORM textures (Occlusion-Roughness-Metallic) for PBR materials. Our Unreal mask map generator automatically creates:

• Red Channel: Ambient Occlusion
• Green Channel: Roughness
• Blue Channel: Metallic

This is the standard Unreal Engine texture packing format used by AAA game studios worldwide. Our free tool generates production-ready ORM maps instantly.
