Color Palette Gridbox Material Generator

This Unity project contains a custom editor tool to generate materials based on a color palette texture. The tool processes each color in the palette and creates corresponding textures and materials.

---

How to Use

Install package from git URL: https://github.com/StephenHubbard/Color-Palette-Gridbox-Material-Generator.git

Suggested: Import "Overlay Patterns" from the Samples tab in your Package Manager.

1. Open Unity and navigate to: Window > Tools > Color Palette Material Generator
2. Assign the following fields in the editor window:

• "Color Palette": A texture containing the color swatches. IMPORTANT: The color palette must be a 1 x N pixel texture. E.g., Each pixel represents a color swatch with a maximum height of 1 pixel.
• "Overlay Pattern": A texture to apply as an overlay.
• "Texture Size": Define the output texture resolution.
• "Render Pipeline": Choose between Built-in, URP, or HDRP materials.

3. Click the "Generate Materials" button.
4. Generated textures and materials will be stored in: Assets/Generated Materials/{PaletteName}/Textures Assets/Generated Materials/{PaletteName}/Materials
5. The materials folder will automatically open in the Unity Project window.

Note: There is a sample scene with ready-to-use materials that can be installed via the Samples tab on the Unity package manager after importing the project.

Requirements

• Unity 2021.3+ (LTS recommended)
• URP or HDRP package installed if selecting those pipelines.

---

Troubleshooting

• Ensure textures have "Read/Write Enabled" in import settings.
• Set "Non-Power of 2" to "None" for accurate color processing.
• If materials do not appear, check the console for errors.

Note: Textures should automatically be set to these importer setting values during the generation process.

Note: Non-Power of 2 textures is set this way to prevent color inaccuracies when processing to account for Unity's texture compression.
