Lacuna Corp, paulojsam,turning "Infinite" toggle in settings will make terrain generated on-the-go. The generated size of such a terrain could be far more than 512, but only the small part of it (within "Build Distance" value) will be displayed. Terrain has 4*4 km data and build range of 100 works pretty well on average pc. cjrussel14, right now I'm focused on Unity 5, but I've got requests to make Voxeland 4 for Unity 4.6, so most probably I'll undertake it. hopeful, got your screen and specs, will try to find out what's that. Could not reproduce it yet on any pc my colleagues or me have access to.
