Streamline your HDRP material workflow. This editor tool visually combines Detail Albedo, Detail Normal, and Detail Smoothness maps into a single, HDRP-ready Detail Map texture—directly inside Unity.Designed for HDRP detail map generation. Functions in all render pipelines but only utilized by HDRP's material system.Stop packing channels manually. The HDRP Detail Map Generator automates the entire process inside Unity.From Separate Maps to Detail Map in Seconds: Intuitive drag-and-drop interface. Assign your textures, and export — no technical hurdles.True Roughness Map Support: Your existing PBR textures (including free ones) work out of the box. No more inverting channels by hand.Built for High-End Projects: Handles massive 16K textures, giving you the detail needed for close-up shots and AAA quality.Exports Organized Assets: Automatically names and saves textures logically, eliminating file management chaos.Supported Unity Versions: 2019.4 LTS and newer (including Unity 6).Render Pipeline: Primarily for HDRP. Tool functions in URP/Built-in, but output is HDRP-optimized.Texture Resolution Support: Up to 16K on Windows and macOS.Input Formats: Recommended – PNG, TGA, and EXR; not recommended: JPG (lossy compression degrades PBR texture accuracy).Output Format: PNG.Note: This tool has been developed and tested on Windows and macOS. Linux compatibility has not been verified and is not currently supported.This asset was developed with the assistance of AI tools.AI Tools Used:DeepSeek (for code assistance and draft documentation generation) and Doubao (for generating source material used in creating blurred background elements of promotional images).AI-Generated Content:Initial code frameworks for basic C# utility methods (e.g., tool interface UXML/USS, texture reading/saving logic).Initial code structures for ComputeShader property declaration functionality.Draft text for the initial user manual.Core Modifications and Value-Added Work by the Developer:Complete Refactoring & Optimization: All AI-generated code underwent deep refactoring to ensure compliance with Unity HDRP best practices, high-performance standards, and C# coding conventions.Core Algorithm Implementation: Manually authored and optimized the core algorithms and blending logic for generating Detail Maps (Detail Albedo, Detail Normal, Detail Smoothness).Deep Unity Engine Integration: Developed a fully-featured custom editor (EditorWindow) to implement a user-friendly workflow.Robustness Enhancements: Added comprehensive input validation, error handling, and progress feedback.Full Cross-Version & Cross-Platform Compatibility Assurance: The plugin has been systematically tested and adapted during development across Unity 2019.4 LTS, 2020 LTS, 2021 LTS, 2022 LTS, 2023 LTS, and newer versions including 6000 LTS, ensuring core functionality remains stable across HDRP iterations. Full functional verification has also been completed on both Windows and macOS systems, guaranteeing reliability across operating systems.Final Documentation & Examples: Rewrote and refined all documentation, and created step-by-step tutorial examples.
