URL: https://polyscann.com/studio/mask-map-generator

Pack AO, roughness, metallic, smoothness, and mask data into one RGB or RGBA texture for a game engine. The online channel packer includes ORM, RMA, Unity HDRP, and Unity URP presets.

## Presets

- Unreal Engine ORM: red ambient occlusion, green roughness, blue metallic.
- Unity HDRP mask map: red metallic, green ambient occlusion, blue detail mask, alpha smoothness.
- Unity URP: red metallic, green ambient occlusion, alpha smoothness.

Upload the available source maps, choose a preset, check the channel preview, and export PNG or TGA. Roughness is inverted to smoothness for Unity presets.
