The X Rebirth Catalog Tool 1.10 is a utility developed by Egosoft for managing and extracting game data from .cat and .dat files. While originally designed for X Rebirth, it is widely used by the modding community for X4: Foundations to unpack game assets for modification. Key Features and Usage
Unpacking Game Files: The tool allows users to extract the entire game directory into a readable format. This is a foundational step for modders looking to inspect or change game assets like models, textures, and scripts.
GUI Interface: Version 1.10 includes a graphical user interface (GUI) that is generally considered self-explanatory. Users can simply select the catalog files and choose a destination path for extraction.
Modding Workflow: In tutorials for building custom ships, such as those found on the Egosoft Forums, the tool is used alongside other utilities like the XRConverter to transform extracted models into formats compatible with 3D modeling software. Technical Recommendations
Path Formatting: When unpacking files, it is highly recommended to create a separate folder for the unpacked game (e.g., C:\X4Unpacked) that contains no spaces in the file path. Some subsequent conversion tools may fail if spaces are present in the directory name.
Root Directory: For advanced modding, once files are extracted, tools like the XRConverter are often placed directly into the mod's root directory to process the models.
