@maticodes @EnvAgencyGeomat @ephtracy I used FileToVox with LazyGUI to generate the vox file from the lidar/buildings image, using the buildings colour image as the source of colour. The vox file can then be dragged into MagicaVoxel and rendered!

@mspry_ @LichfieldsUK @HarryJBennett Really interesting article. ONS Nomis major towns and cities pop estimates appear to be based on output areas rather than MSOAs.
