This is a project that initially started as a hobby project, to see if I could create an efficient voxel engine for Unity. Initially, I planned on selling this on the Unity asset store, however life happened suddenly and I'm unable to work on this as much as before, if at all. So here it is, open sourced under the MIT license. You're free to use it for commercial use, however I'd really love to hear about any project using this. Thanks! Suppose I'll keep the important updates here. 4/14/2014: Uploaded project to GitHub. Known Bugs: Editing terrain with NodeEditor does not work if the initial voxel width is not 1.
