Shader Properties
Color 1 and Color 2 define the colors of the two tiles.
U Frequency [0..+∞]
V Frequency [0..+∞]
U Frequency and V Frequency define the size of tiling, i.e., the fineness of the structure, in two independent directions. Higher values result in smaller tiles. Enter unequal values, such as U=1 and V=2, for rectangular tiles.
