Tile geometry has to be selected at tile object slot.FStorm Tile Bump texture is used to generate bump or displacement mapping for tiles.Tiles height set tiles depth/thickness.Tiles slope sets tiles chamfer/slope.Tiles slopes can be controlled with a map and map power.Edge softness control how smooth tiles edges are.Random tilt rotates tiles surfaces in random directions.Concavity producesconcavity/convexity effect on tiles surfaces.Seams height sets how high seams(grout) are relative tiles level.Seams slopesets transition between tiles and seams levels.Height map allows to control seams levels with a map.
