The usual way to make infinite skyblock islands in Roblox is to use a chunked spawning system: generate a new island only when the player gets close to an edge, then keep extending the world in a grid or ring pattern so islands do not overlap. A Roblox DevForum example describes this as spawning islands “far distance away” from the player and continuing as they travel, often by using anchored reference points or attachments to decide the next island positions.

Simple setup

  1. Place a starting island in the center.
  2. Define spawn points around it, like north, south, east, and west.
  3. When a player approaches one side, create a new island at the next position.
  4. Store generated island locations so you do not duplicate them.
  5. Use a seed or random offset to vary the layout while still keeping spacing consistent.

Common pattern

A practical approach is to build each island from a template and spawn it with something like a grid step, for example every 4000 studs, which is the kind of distance mentioned in the Roblox DevForum discussion. That keeps the generation predictable and makes cleanup easier, because you can destroy or unload islands that are too far away.

Basic Roblox idea

In Roblox Lua, the logic usually looks like this in plain English:

  • Detect player position.
  • Convert that position into a region or tile index.
  • Check whether that tile already has an island.
  • If not, clone an island model and place it there.
  • Mark the tile as generated.

Important note

If by “Roblox” you mean the game Islands/Skyblock itself rather than making your own Roblox game, then you generally cannot truly generate infinite islands unless the game’s own mechanics allow it. Public videos about Roblox Islands often discuss resources, duplication, or “infinite” methods, but those are not the same thing as procedural world generation.

Safe recommendation

If you are building your own skyblock experience, keep it fair and stable by:

  • Limiting active islands near each player.
  • Using a deterministic seed.
  • Saving generated chunks.
  • Spawning islands on a timer or trigger, not every frame.

A good mental model is: the world is endless, but only the part around the player is real at any moment. That is the standard way to simulate infinity without lag.

TL;DR: Use procedural chunk spawning, generate islands on demand near the player, and save which positions already exist so the world feels infinite without actually loading everything at once.
