I'm new to Blender, and I'm building a digger model for use in Unity. It's for iPhone so I'll want to have it as a single mesh with a single material. I'm in the process of unwrapping it for texture painting, and it strikes me that I can save texture space by repeating some of the textures such as the track texture could be mapped to both left and right tracks, both inside and outside. I understand I can unwrap them all and then manually align those 4 UV maps together so they share the same texture space, but is there a way to 'sync' vertices - i.e. tell Blender that a certain vertex on the left track should always have the same UV as the corresponding vertex on the right track when unwrapping?

1I think you should consider asking this in Blender forums too. I think most people in here are Unity3D developers, not Blender users.
I co-work with a Blender artist, but I would imagine him saying: check a YouTube tutorial on that subject. Everything is videodocumented for Blender (or well… almost)
