I don't really know what to do from here. I have modeled a train made from multiple meshes. I also have animations, but don't know how to make them into Actions. I also get multiple meshes, when I export it as it is, so I think the meshed need to be joined together in order to have a single mesh after exporting. But how can you have one single mesh, when you still need have seperate wheels that spin?

I'll attach the mesh, so you get an idea on what I'm trying to do. Actually I'm just trying to export it as it is and have it work ingame, or at least Ogre Meshy, with spinning wheels animations.
