Resources

Resources are the data files that the Hedgehog Engine loads things like 3D models, textures, animations and any other kind of data from. Many of these resources are stored in proprietary formats optimized for fast loading times, and thus require special tools to be edited by modders. Many of them are also built using proprietary SEGA technologies, like the ASM animation system. On this page we provide a list of all known resources supported by the Hedgehog Engine, their support in various games and tools that can be used to edit them.
