This is a simple Bricks and Mortar texture that can be applied to reliefs.  There are parameters to set the size and position of the bricks.  Additional parameters allow you to set the roughness of the bricks and mortar as well as introducing some distortion into the brick pattern.

Parameters :

Position : Position of the texture.

Scale : The texture is scaled by this value.  Use this one along with Brick Size and Mortar Size to get the effect that you want.  The roughness and distortion of the bricks and mortar will also be scaled when you use this parameter.

Brick Size : Nominal dimensions for the bricks.  Actual size of bricks is determined by the combination of Brick Size and Scale parameter.

Mortar Size : Nominal dimensions for the mortar.  Actual size of mortar is determined by the combination of Mortar Size and Scale parameter.

Jitter : Strength of the distortion added to the brick pattern.  Higher Jitter value will produce more distortion.  Use this in combination with Twist parameter to define distortion.

Twist : This determines the tension in the distortion pattern.  Higher values here make the distortion pattern smaller and "tighter".  Use this in combination with the Jitter parameter to define distortion.

Brick Rough : Strength of the roughness applied to the bricks.

Mortar Rough : Strength of the roughness applied to the mortar.

Notes : If you get a combination of parameters that are acceptable and want to make the brick pattern bigger or smaller - use the Scale parameter to scale the bricks and distortion and roughness together.  With the use of distortion, the brick texture can produce interesting patterns that look nothing like bricks and mortar.
