The File Editor is a document viewer and manipulator for modifying any REDengine file. WolvenKit is the only RTTI-based editor for RED4.
Using the File Editor
REDengine files can be viewed by double-clicking them within the Project Explorer. The File Editor expects unbundled files with compressed internal buffers, so we recommend using files added to the project using the Asset Browser to ensure compatibility.
After making changes to a RED4 file, use the Save File or Save All button within the General section of the Ribbon to save changes. The document can then be closed, and packed with the mod project.
