About
Contains all the essentials. This contains light sources, object descriptions, names of their corresponding textures and shaders, portals, and sectors.
Technical information
- Format version: 14
- Stores visual geometry in *.ogf format. Limitations and features are similar to *.ogf files without skeleton.
- One mesh can store only one material.
- The format stores visual geometry, collision geometry, sectors, portals, dynamic light sources, glow objects.
