What’s the best way to delete unused materials, textures and 3d meshes?

There are various utilities that do this sort of thing on the marketplace ( can’t find one right now ).

But if you want to keep your package size down, make a new project and migrate your maps to it. That way only the stuff used by the maps will be transferred.

EDIT: Assets Cleaner - Project Cleaning Tool in Code Plugins - UE Marketplace
