A grid will be generated and filled randomly with the selected blocks. Each block will be colored so that it connects smoothly with surrounding blocks, no matter which direction it is facing or which blocks are placed.
Every generated grid with an even Grid Size will connect to its own edges, so you can create a repeating pattern made up of one grid.
Click the blocks under Selected Blocks to toggle which blocks will be used.
Changing Block Pattern will affect how blocks are oriented, instead of orientation being random.
If Allow Corner Mixing is checked, then a single block can have different types of corners, instead of both corners always being the same.
