Mask Map Generator

The Mask Map Generator is a lightweight Unity Editor tool for creating high‑quality mask maps directly inside the engine. It provides real time previews, per‑channel controls, and customizable output resolutions, making it easy to generate consistent, production ready textures without relying on external software.

Includes full texture packing support. Because it outputs standard texture maps, the generator is fully pipeline agnostic and works with Built‑in, URP, HDRP, and custom SRPs.

The tool integrates smoothly into a wide range of material workflows, including Shader Graph setups, custom shaders, low poly and high poly assets. Its output is ideal for detail rich materials, stylized surfaces, and even tessellated or displacement driven shaders that benefit from clean, well defined mask channels.

This package includes the generator tool, a clean 4K grass mask map example, and documentation to help you get started quickly. Suitable for any project or genre that uses PBR materials, stylized shaders, or custom texture workflows.
