This tool came about with the need to make the Baked Volumetrics effect no longer dependent on sampling from light probes in a scene. So building a voxel-based raytracer was necessary, and here we are. The raytracer is implemented all with Compute Shaders (NO RAYTRACING HARDWARE UTILIZED), so as long as the hardware supports compute shaders (most hardware now does) it should work on any GPU regardless of vendor which is the goal. It's worth noting that this tool serves as a foundation for potentially more things to come in the future (Real-time Voxel Based GI, Voxel Based Specular Reflections, Voxel Lightmaps, Scene To Voxel Mesh, etc.)
