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 produces concavity/convexity effect on tiles surfaces.

Seams height sets how high seams(grout) are relative tiles level.

Seams slope sets transition between tiles and seams levels.

Height map allows to control seams levels with a map.
