Diablo 4 Texture Extractor

What it does

The Diablo 4 Texture Extractor is a tool that extracts and converts .tex files to PNG, WebP, or JPG formats. It can also slice the files into separate image files when applicable.

Known Issues

• Some of the intermediate DDS files might not be valid, which can cause texconv to fail.
