| - | These can be used to create holographic projections in a resolution of 48x32x48, over a maximum area of 9x6x9 blocks. Holograms are defined via 48x48 32-bit bit masks, where each bit defines whether the voxel at that height should be on or off. Tier two holograms do not provide a higher resolution, instead they allow using up to three colors in the displayed hologram (as opposed to just one for the tier one hologram). | + | These can be used to create holographic projections in a resolution of 48x32x48, over a maximum area of 9x6x9 blocks.
