Although not a building material (yet), the glass props will enable players to put windows into their homes or construct any number of transparent creations. A more widely applicable change, however, is the ability to remove the air when putting down templates or pasting something. Previously, empty space in a template counted as a voxel itself, meaning that the space would be placed or pasted along with the filled voxels. While helpful in some cases, this same principle caused undesirable effects when trying to combine templates.
As promised previously, the light orbs that were made available for purchase in the Showcase last week can now be crafted in game. Additional tweaks and fixes, including a UI compass, are detailed in the update notes.
