Using the Spatial Thermometer in Fortnite Creative

The Spatial Thermometer is a method for displaying and managing memory across your island. The island is divided into cells (equal to a grid tile), and a heatmap can be displayed that shows how much memory each cell is using. Instead of just having an overall memory limit, you can adjust the amount of memory used cell by cell. This gives you greater flexibility when you are building complex islands that use a lot of memory.

Spatial Thermometer

The Spatial Thermometer memory management system measures memory cell by cell, comparing the memory use of each one to the cells next to it. Instead of loading everything in the island and storing it, the island will only use memory to store what is seen and used. It unloads unseen props and terrain from memory. As players move around the island, the system only loads things the player can see and interact with.

Prop and Device Memory

The Spatial Thermometer breaks an island down into a grid of cells. Each prop you place has a memory cost that affects the area around it, within a specific radius. When you place a prop, its memory cost is added to all the cells around it from which it can be seen.
