Bricks: 1 - 64Sets the amount of bricks in both X- and Y-axes.
Bevel: 0.0 - 1.0Changes the bevel profile for the bricks, allows for changing in two directions as well as setting falloff profile and corner rounding.
Keep Ratio: False/TrueMakes the Bevel profile tied to brick size or not.
Gap: 0.0 - 1.0Gap to leave between bricks. Keep in mind Bevel also introduces a gap, so setting bevels too means you have to compensate with this parameter.
Middle Size: 0.0 - 1.0Brick pattern offset, changes size of every other column or row.
Height: -1.0 - 1.0Modifies height profiles. Allows for introduction of Luminance variation and all kinds of randomisation.
Slope: -1.0 - 1.0Introduces a slope on a per-brick basis, as if certain bricks are lying at an angle.
Offset: 0.0 - 1.0 Offsets bricks on a row-basis, affects per-row spacing.
Non Square Expansion: False/True Enables compensation of squash and stretch with non-square ratios.
