i have a 2s array with a rectangle clipping area and a square tile as the segment. the square tile has a multi-sub-object material with 4 materials. the segment is connected to a material node to randomize between 1 and 4 material id's.
i'd like to rotate the square tiles randomly, but only every 90degrees - so 0degrees, 90degrees, 180degrees, 270degrees to add more variation to the floor.
if i use the random rotation it does it by small increments and therefor the tiles do not line up. i saw someting about exporting parameters and using the on/off with a mirroring, but didn't quite get the results i wanted.
