Shader Properties
Load the texture that you want to make "coarse" here.
This option is important when animating the Tile U/V option since interim values (e.g., 5.44 at frame 3 and 6.23 at frame 4) can result. If this option is active only integer values will be used (e.g., 5 and 6 in our example), resulting in no overlapping tiles.
Tiles U [1..+∞]
Tiles V [1..+∞]
Use these options to define how many tiles should be created in the U and V direction (horizontal or vertical).
