Here are stylized materials I made in 2018 for the Castle theme in Diabotical. These were among some of the earliest content I created for the game.
Many of these materials could blend between eachother via the use of channel packed masks that you scaled and blended by float variables in the material file. For use with the block system in the map editor material blending was static so you had to create all the blending options you wanted in the masks and then scroll the UV co-ordinates of blocks to change the blending.
