This asset allows you to draw 3D voxel objects using ray casting. The asset is made specifically to work well with conventional 3D games, allowing for a combination of voxel sprites and triangle meshes.
The voxel sprites can be transformed like any other 3D object using matrices. Even if the object is transformed, the actual voxels will still be rendered in world-space, resulting in a lovely low-resolution effect when the object rotates.
The asset has only been confirmed to work on Windows.
Thanks to: kraifpatrik, for showing that you can set the depth of individual pixels in a shader!
