Is it possible to export a terrain complete with models and animation into another Unity project?
My project consists of two worlds and to save time my work partner did one while I developed the other and now we need to combine them into one project. How can we do this without losses?
Extra question: How can I give objects a glow? The simplest way possible would be very much appreciated! I know there’s a standard glow in Unity but I’m a complete noob at this so I have no idea where it is or how to apply it 
Exporting/Importing assets - AssetBundles. (Look on Asset tab in Unity)
As for the glow, it depends if you have Pro (glow shader) or not. Free is just limited to Halo + Lens Flares.

Actually assetbundles are the wrong thing, you want to use packages.
Just select what you want to export, then go to Assets and use “Select dependencies” and then “export package”
and on the other side “import package - custom package”
thanks a bunch for the halo effect! Exactly what I needed
