What It Does

Texture Channel Packer helps artists and technical artists combine separate grayscale maps into packed textures for realtime material workflows.

Common layouts include:

• ORM: occlusion, roughness, metallic
• RMA: roughness, metallic, ambient occlusion
• Custom RGB/RGBA channel assignments
• Alpha, height, mask, and utility texture packing

The tool is designed for quick browser-based workflows. Drop in source maps, assign channels, preview the packed result, then export an engine-ready texture.

Typical Uses

• Pack material masks for Unreal Engine, Unity, Blender, glTF, or custom shaders.
• Rebuild ORM/RMA textures from separated source maps.
• Create compact texture sets for web, realtime, or asset delivery pipelines.
• Verify channel assignments before handing textures to another artist or developer.
