3D volumetric map editing in Unity Editor

In this short demo I will be showcasing a new Unity Editor tool that I have developed that allows you to paint and sculpt 3D volumetric voxel terrain in the editor that can then be modified at runtime (not showcased here). This is a stripped down version of my own GPU Procedural Voxel Terrain package but without the GPU generation and without LODs or octrees, just a fixed sized map that is serialized in the editor and deserialized at runtime. Currently no map compression built-in but I will implement some sort of delta compression for the density values and RLE for the material values.
