im adding voxel-based resource-based economy/subsystem
it is based on voxel data/calculations despite no real voxels in the game
material information is only used for processing and tracking resources (and eventually for analytics and prices calculation)
i already can create crushed stone from stone block and that also gives some sand as a by-product, all technically based on volumetic data (its interesting that it doesn't have millions of voxels, instead it is recording them like numbers (like paper currency vs metal coins))
