What is ATA?

AdvancedTextureAssignTool is a Unity editor tool that helps you quickly set up and assign textures to your materials. Instead of doing everything by hand, the tool finds, matches, and packs the right textures for you, no matter what shader you’re using. I use it when making my assets, and you should use it for yours too. It saves time and ensures your materials always look great.

Why use ATA?

Setting up textures for many materials can be slow and confusing. With this tool, just put your textures in a folder, and it will automatically match them to the right slots on your materials. It even knows how to handle special texture types (like metallic, roughness, and mask maps) and can batch process many materials at once. You can also make your own rules for how textures are matched.

How Works

• Inverts Roughness Maps: If your workflow requires a smoothness map (like Unity Standard) but you only have a roughness map, the tool automatically inverts the roughness texture to create a smoothness map.
• Packs Metallic + Smoothness: Combines metallic and smoothness into a single texture channel if your shader requires it (for example, Unity Standard and HDRP).
• Creates Mask and ORM Maps: Automatically creates HDRP Mask Maps (metallic, occlusion, detail mask, smoothness) and glTF ORM Maps (occlusion, roughness, metallic) when needed.
• Combines Alpha and Color: Can merge a separate alpha (opacity) map into your color texture so transparency just works.
• Fixes Normal Maps: Detects and marks normal maps properly so Unity recognizes them as such.
• Deletes or Keeps Originals: You can choose to delete processed textures or keep the originals for safety.
• Smart Detection: The tool uses advanced rules to figure out texture types by filename and packs or assigns them accordingly.

More Features

• Automatic Texture Matching: Finds and assigns textures to your materials by looking at their names.
• Smart Map Packing: Can combine different textures into one (like metallic and smoothness) for better performance and shader support.
• Batch Processing: Set up lots of materials at once with just a few clicks.
• Custom Rules: You can add your own keywords or rules to match unique texture names.
• Works With All Shaders: Supports Unity’s Standard, URP, HDRP, and even custom shaders.
• One-Click Revert: Go back to your original textures anytime if you want.
• Handles Transparency: Automatically combines alpha and color maps if needed.
• Helpful Logs: Shows you clear messages about what’s happening.
