New demo of my toying with an Octree-based LOD scheme. Use WASD + arrows and QE to steer the "space ship". The texture stretches badly and you'll see holes, but you'll also see a decent sized moon! @Zynx: look in the "DoSculpt" function and play around with the minX, minY... lines. The first value in the Mathf.Max() and Mathf.Min() control which voxels in the block can be sculpted. By default they're 0 [array dimensions], but setting them to 1 and [dim]-1 or such might be just what you're looking for!
