Concepts

Concept pages discuss how FoundryEngine works. They do not show step-by-step instructions (that is the guides section) and they do not list API details (those are in guides too). They answer the "why" and "how does it fit together" questions.

Read these in any order. Each page is self-contained.

• What is a bundle?: the model that makes a mod a content pack.
• Bundles to registry pipeline: how scripts become registered content and generated data.
• Editor authoring model: how the in-game editor writes what the engine systems consume.
• Network and persistence: how server state stays in sync with clients.
• Stages and progression: how stages gate content and sessions orchestrate it.
• Runtime worlds: how custom worlds are created and sandboxed.
• Sandbox and security: what bundle scripts can and cannot do.
• Rendering pipeline: how depth, effects, particles, and the skybox compose.
