Gradients with Pattern Tool
From MagicaVoxel Community Wiki
Gradients can bring life to many voxel creations and add a nice touch to any scene. This works both in nature and urban scenes. Gradients can enhance water, rocks, grass, walls, and many other things.
Pattern tool provides one of the easiest ways to create gradients.
First, select Pattern tool in the Brush panel or press P on your keyboard. Then choose Selection tool in the same panel or press N. Make sure the selection type is set to Box.
Select as many voxels as you like — later those will be your pattern with which you will create your gradient. You can either select some random voxels or create some sort of, well, pattern, depending on the final look of the gradient you are looking for. If your gradient will not be applied to a flat surface, it's best to select less voxels.
