Engine Resource editors allow to edit ALL resource files of a given type for which a matching module exists in the engine to load this file. They are thus Game Independent.

• Rig (edit engine rig resources)
• Skin (edit engine skin resources)
• Font (edit engine font resources)

Epsylon editors allow to edit definition files used by the Epsylon game. Most of them are though also useful for other games. Loader scripts are available to load these definitions in your game.

• World (edit Epsylon worlds, *.world.xml)
• Animator (edit Epsylon animator definition, *.animator.xml)
• Sky (edit Epsylon sky definition, *.sky.xml)
• Particle (edit Epsylon particle emitter definition, *.partem.xml)
• Speech Animation (edit Epsylon speech animation definition, *.spa.xml)
• Conversation (edit Epsylon conversation definition, *.conversation.xml)
