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.

Levels

Levels are a new system in Sonic Frontiers and up that allow the game to dynamically load other resources when they are needed. They specify which resources need to be loaded to load a certain "level". This is a system similar to Unreal Engine's level system.

Resource types
Name	Description	Extension	Engine name	Editing tools
Level	A special resource that's only used to check whether a level has been loaded in the engine. It does not contain any data.	.level	ResLevel	N/A
Master Level	Information about levels: which levels depend on each other, and also which packfiles to load in order to load a level.	.mlevel	ResMasterLevel	KnuxTools Restoration Issue Pocketknife

Configuration Parameters

Resource types
Name	Description	Extension	Engine name	Editing tools
Reflection	Reflection-enabled configuration data. Contains parameters that can be edited by developers without changing game code.	.rfl	ResReflection	DevTools Restoration Issue Pocketknife 010 Editor templates

Set Objects

Set object data is what specifies where game objects are placed and how they are configured. This is what you'll be editing most when making a stage mod.
