Project Overview
This tool was developed as a small editor utility to automate a common task when working with utility textures in Unreal Engine 5.
Packed textures such as ORM maps, masks, or other data-driven textures should not use the sRGB color space. When handling large numbers of assets, manually disabling this setting can become repetitive and error-prone.
The tool allows artists to process selected folders directly from the Content Browser and automatically disable the sRGB setting on compatible Texture2D assets in batch.
It was implemented using Python scripting integrated with an Editor Utility Widget Blueprint, providing a simple interface directly inside the Unreal Editor.
Technical Stack
- Engine: Unreal Engine 5
- Language: Python (Unreal Python API)
- Key System: Unreal Editor Utility Widget + Python scripting integration
- Optimization: Batch processing of assets through the Content Browser
Challenges & Solutions
1. Handling Large Asset Collections
When working with large projects, selected folders can contain hundreds or even thousands of
assets. Running batch operations without feedback can make the editor appear frozen and provide
no indication of progress to the user.
Solution: The tool integrates Unreal’s ScopedSlowTask system, which provides a
progress bar directly in the editor. This allows artists to monitor the operation in real time
and cancel the process if needed. This improves usability and aligns the tool with common Unreal
Editor workflows.
2. Safely Modifying Only Compatible Assets
Folders inside the Content Browser often contain multiple asset types. Attempting to modify
properties on incompatible assets could result in errors or unintended behavior.
Solution: Each asset is loaded and validated to ensure it is an instance of
Texture2D before applying modifications. This filtering step ensures that only relevant assets
are processed and prevents the tool from attempting to modify unsupported asset types.
