Purpose

Why use a chunk loader?

A chunk loader is a performance optimization system that splits a large game world into smaller, manageable pieces (chunks) and only renders the ones near the player.

Why use one?

1. Memory Management: Roblox has a part limit. Keeping a massive map in Workspace at all times can crash mobile devices or cause high memory usage. By moving distant chunks to ReplicatedStorage, you free up significant memory.

2. Improved FPS: The engine doesn't have to calculate physics or render geometry for things the player can't see. This leads to higher frame rates, especially on lower-end hardware.

3. Reduced Physics Lag: Unloaded chunks don't process collisions. If you have thousands of moving or interactive parts, a chunk loader ensures only the ones near the player are "active."

Chunk Loaders vs. StreamingEnabled

Roblox has a built-in feature called StreamingEnabled. While it does something similar, a custom chunk loader (like the one we built) is often preferred for:

1. Control: You decide exactly when and how things appear (like the fade effect).

2. Reliability: You don't have to worry about scripts breaking because a part hasn't streamed in yet; you control the parentage.
