The Brick Procedural generates an infinite brick pattern with custom control over the random distribution of the bricks, their offset and their texture, that can be used as a color texture or in grey scale as a bump, displacement, weight map or mask texture.
...
For each individual brick, the procedural picks a fraction of the given texture and can even apply a random rotation to the texture (in increments of 90 degrees) so it avoids getting unnatural regular patterns and texture repetitions.

Brick Procedural parameters
- Preset: Several Brick presets to choose from. Useful as an starting point to customize your own brick textures.
- Blending Factor: Blends a percentage of the current procedural with the result of the procedurals below in the stack.
- Brick Width: Defines the width Width of the bricks. brick in UV coordinates (coverage percentage ranging from 0 to 1).
- Brick Height: Defines the height Height of the bricksbrick in UV coordinates (coverage percentage ranging from 0 to 1).
- Brick Offset: Defines the lateral offset between two consecutive rows of bricks (in percentage of the brick width). A value of 0 would apply no offset between two rows, producing a tiled look, while a value of 50 offsets each row 50% the width of a brick, producing a standard brick look.

- Random Offset: Randomizes the rows offset by a percentage of the Brick Offset parameter.

- Double Brick: Enabling this option produces a double brick pattern, inserting an small brick after each regular brick. The width of the small brick is defined by the Small Brick Width parameter.

- Round Corners: This option smooths the brick corners by applying bilinear interpolation on the edges sampling. See example below.

- Transition Sharpness U and V: Blurs the brick-mortar transition in U and V directions. A value of 1 produce a perfectly sharp transition while a value of 0 produces a completely blurred transition. This blur is vectorial, so it is independent from the resolution.
- Boundary Noise Detail: Amount of noise generated in the brick-mortar transition. This noise is vectorial, so it is independent from the resolution.
- Boundary Noise Region U and V: Thickness of the noise applied to the brick-mortar transition in U and V direction, in percentage of the brick's horizontal/vertical dimension. A value of 1 expands the noise region all the brick dimension long.
- Seed: Initial value used for the generation of random numbers computed by the brick procedural.
- Random Rotation: To avoid getting texture repetitions, this checkbox allows you to automatically apply a random rotation (in increments of 90 degrees) to the brick texture before applying it.Color

- Brightness Variation: Applies a random brightness adjustment to the brick color or texture before applying it, getting a more random result. This value represents the percentage of that brightness adjustment.

- Brick Color 1, 2 and 3: Sets the colors for the three brick elements that will be randomly distributed.
- Brick Texture 1, 2 and 3: Sets the textures for the three brick elements that will be randomly distributed.
- Sample Size 1, 2 and 3: Size of the random patches of texture used on the brick, in percentage. A value of 10 will pick a random patch of 10% the size of the input image randomly inside the input image for each brick, while a value of 100 will put the whole texture image on each brick.
- Weight 1, 2 and 3: Relative weight for the 1, 2 and 3 brick elements to control the presence of the bricks 1, 2 and 3 on the final pattern.

Image Added | Image Added | Weight 1, 2 and 3 set to 100, 100 and 100 (left) provides the same presence to the three bricks, while weights set to 100, 60 and 15 gives Brick 3 less presence (right) |
|
- Mortar Thickness: Defines the width in meters of the mortar between bricks.
- Mortar Color: Sets the color for the mortar.
- Mortar Texture: Sets the texture to be used for the mortar.
