This release adds a new Paste as Single Material option, and fixes several issues including resolving a shader compilation issue on Intel UHD 630 integrated GPUs (and likely other Intel GPUs of a similar generation / driver). This caused the 3D rendering of voxels to fail, so the world appeared empty.
To use Paste as Single Material open the menu Tools > Edit Tool > Shapes
Copy some voxels or use File > Load World as Paste Brush... to create a paste brush.
Select Paste as Single Material and use the Palette to select your material
Click Do Paste (or if not using an anchor left click in the 3D view to paste)
This can be used along with the Randomise Materials Modifier
Note that the paste brush preview currently doesn't show the selected material.
Using paste as single Material example: the multicolored blue tractor is pasted as red, gold etc. single materials. The yellow cornfield is copy/pasted in red with an overlap. Modified original model by Rebecca Michalak.
