Project Size Tool

A project’s total size includes all assets, the terrain, and game mechanics supported by Blueprint functionality. These elements all contribute to project size and use memory. Large detailed assets that use a lot of data have the largest effect on the performance of an island and contribute heavily to a project’s size.

The Unreal Editor for Fortnite (UEFN) Project Size tool uses a graph to illustrate the size of different asset types in relation to the project's overall size. Use this information to decide which files to compress further or which assets to edit to decrease their data footprint.

To learn more about your island’s memory usage, see the Memory Management page.

Project Size Tool

To see a project’s size, the island first has to cook, render, and play to calculate how the assets in your project contribute to memory usage.

Launching a playtest session provides a way for you to cook your assets and access the Project Size tool.
