File Modification & Generation¶
CLS, PROP, and SSO files can be edited via Property Control — this panel automatically appears when opening any of these file types.

Property Control allows you to:
- add or remove properties from CLS files,
- edit properties values in PROP files,
- modify game logic in SSO files.
RES files are automatically generated or updated by the editor during object export (i.e., when you save changes). In some cases RES files are essential — mods that change game assets (textures, models, sounds) won't work without them.
The next section explains the inheritance in CLS, PROP and SSO files.
