The Grid Procedural generates an infinite regular grid pattern with custom control over the repetition and colors, that can be used as color texture or in grey scale as a bump, displacement, weight map or mask texture. 

Examples of the Grid procedural in use, both as color texture (left and middle) and as mask and bump texture (right) 

Grid Procedural parameters 

• Blending Factor: Blend percentage of the current procedural with the result of the procedurals below in the stack. 
• Cell width and height: Defines the width and height of the individual cell. 
• Horizontal lines: Enables the creation of horizontal lines. When disabled, only vertical lines are created. 
• Boundary thickness V: Thickness of thle horizontal grid lines. 
• Verticall lines: Enables the creation of vertical lines. When disabled, only horizontal lines are created. 
• Boundary thickness U: Thickness of the vertical grid lines. 
• Boundary sharpness: Defines the sharpness/blurriness of the boundary transition. Values vary from 0.0 to get a blurry transition up to 1.0 for a crisp sharp transition.
