Streamline your HDRP material workflow. This editor tool visually combines Metallic, AO, Detail Mask, and Smoothness maps into a single, HDRP-ready Mask Map texture—directly inside Unity.

HDRP Mask Map Generator transforms a complex, multi-step process into a fast and reliable workflow inside Unity.

Core Features:

• Visual, No-Code Workflow: Drag and drop your Metallic, AO, Detail Mask, and Smoothness (or Roughness) maps. See them merge into a perfect HDRP Mask Map in real-time — no manual channel packing or external software needed.

• Native Roughness Support: Works seamlessly with free PBR texture libraries by directly accepting Roughness maps, automatically converting them to the Smoothness your HDRP materials require.

• High-Fidelity Output: Support for textures up to 16K resolution on both Windows and macOS ensures your assets retain all their detail.

• Smart Export System: Automatically generates organized file names and saves in your preferred format (PNG), keeping your project tidy.

Ideal For: Technical Artists, Environmental Artists, and solo developers who want to build HDRP materials faster, with fewer errors, directly in the editor.
