A one-click Unity Editor tool to split HDRP Detail Maps into separate PBR textures (Desaturated Detail Albedo, Normal, Smoothness), saving hours of manual work and ensuring perfect channel extraction.
The HDRP Detail Map Splitter is a powerful Unity Editor extension that intelligently deconstructs HDRP-standardized Detail Maps. It extracts the Desaturated Detail Albedo, Detail Normal, and Detail Smoothness channels into separate, ready-to-use PBR textures. Save hours of tedious Photoshop work and achieve perfect channel separation through precision automation.
Core Features:
One-Click Splitting: Instantly split all channels from a packed Detail Map.
Pixel-Perfect Accuracy: Eliminate manual errors in channel separation.
Flexible Output: Choose your preferred Smoothness/Roughness workflow.
High-Resolution Support: Process textures up to 16K resolution on both Windows and macOS.
Smart Saving: Automatically generates organized file names and saves in your preferred format (PNG), keeping your project tidy.
Pipeline Agnostic: Generated standard PBR textures work in any pipeline (Built-in, URP, HDRP).
⚠️ Important Note:
The tool outputs the desaturated (grayscale) Detail Albedo, extracted from the Red channel. This is the correct and expected result, as the original color data is not stored in the HDRP-standard packed Detail Map.
Ideal For:
Technical Artists, Environment Artists, and solo developers who need to build materials for HDRP, URP, or Built-in Render Pipeline faster, with fewer errors, all directly within the Unity Editor.
