Help with Magix!

This is a screenshot of my Magix Elementus game originally a Ludum Dare competition entry, I’m going through a phase of polishing and completing my many Prototype and Beta games and I could use some help and advice with this one.

  1. Guide to Optimising the Voxel terrain (currently just cubes) working really fast with textures and lighting?

  2. Turn the Two player game (via keyboard) into a Multi-player Game via networking, so are there any good well documented free tutorials/examples that would get me started with this?

All help must factor in my N00b level of Unity development, preferably be in c# and be very cheap or ideally Free!

Found this massive minecraft voxel thread will have a read it might have just what I need somewhere within it’s 22 pages!

And I’m going to work through the Networking example project, for now!

Found the links to a Minecraft Webplayer and a Unity Package that allows you to try it out are here:
