How to import meshes at runtime?

not sure if this is the right place, since this is my first ever question on here.
I’m looking for a way to import meshes and textures from outside the Unreal Engine at runtime. The meshes will be generated from outside the engine, saved in a certain directory under a certain name and I would then like to load them and assign them to my actors.
I have found RuntimeMeshImportExport in the Marketplace (RuntimeMeshImportExport in Code Plugins - UE Marketplace) but I’m not sure this is what I’m looking for and would rather go for open-source alternative, as this is a student university project.
I’ve also found GitHub - GameInstitute/RuntimeMeshLoader: RuntimeMeshLoader for UE4 which RuntimeMeshImportExport seems to be based upon, but it’s by now outdated.
Any help would be much appreciated (:
