Loading static meshes, collisions and textures into packaged game


Anyone knows if it’s possible to load new objetcs (mesh, texture, collision…) into a packaged game from an external folder? It doesn’t need to be done runtime, but in the loading.
A client is asking for that specific feature, and we don’t even know if it can be done in Unreal.
In case you know about this, it would be also interesting to know if you would be interested in developing this feature with us. And also important, your price.
