I’m having an issue with my Unreal Editor for Fortnite (UEFN) project. My map is currently over the 2 GB project size limit (2.4 GB), preventing me from play testing it.
Here’s what I’ve done to try to reduce the size:
-
Resized textures: Reduced all textures to 1024×1024 (1K).
-
Checked compression: All textures are using BC1 (diffuse) or BC3 (with alpha).
-
Mipmaps enabled: All textures have mipmaps set to “From Texture Group”.
-
Removed unused assets: Deleted unused materials and other assets in the project.
-
Verified skeletal meshes: Only essential skeletal meshes remain; unused LODs/animations removed where possible.
Despite all of this, the Project Size tool still shows the textures as the largest contributors, and the project remains ~400 MB over the limit. The next largest assets are very small (~535 KB).
It seems that the project size is being inflated due to UEFN’s internal packaging/engine overhead, which I cannot reduce manually. I’ve attempted all standard optimization techniques, but nothing is allowing me to get under the 2 GB limit.
Could you provide guidance on how to reduce the project size further, or is there a workaround for projects where optimized textures with alpha plus engine overhead exceed the 2 GB limit?
