Resizing Textures in Unreal Editor for Fortnite

Game textures have specific requirements to render properly in-game. When creating textures in Unreal Editor for Fortnite (UEFN) with imported images make sure the source image file uses the power of two for height and width. This increases the compatibility and stability of your island across platforms.

Compressed file formats for graphics processing units (GPUs) must use power of two textures across all consoles, PCs, and mobile. Textures that don’t conform to the power of two rule will become unstable on lower-end platforms and possibly cause game crashes. Power of two is also used in texture streaming to lower texture resolution on platforms with less memory.

Texture streaming helps with:

• Changing a texture’s resolution.
• Determining how quickly a game loads.
• Increasing the visual quality of the game.
• Saving GPU memory.

What Power of Two Is

Computers and consoles manage and process data in limited chunks rather than all at once. This is a similar principle to how backgrounds are rendered using World Partition.
