Map item help

[Fr4cture]

Alright so I'm making a map and I am using meshes that I have downloaded and were not in the game at the start, every time I export it however my friend tells me they cannot see the downloaded meshes/objects in the map. Am I suppose to put everything I've downloaded into the map folder? For example if I downloaded a rock object and it had the mesh/texture/text file etc do I just put all of that into the map file so my friend can see it?

Sometimes it's enough just to grab the file from exports, however at times when you make a map with custom objects or textures you need to put that in a file too.
I believe there's a possibility to make "groups" of objects and name them after something you want so that it's easier for you to find them, and thereafter put them in your download.
