HOW TO USE GRIDZ

UV coordinates - Your model's UVs after unwrapping it. This is important to ensure the grid follows the object's shape as best as possible.

Object coordinates - Object coordinates of your model. This is used to apply the default roughness map.

SURFACE

Base color - Background color

Grid color - The color of the lines and markings.

Metallic - Your usual metallic value. 

Custom roughness - Toggle to set your own roughness instead of the default. 

Roughness - Custom roughness value. Works like your classic roughness on a Principled BSDF.

Emission strength - Emission value for the grid lines and markings. 

Make transparent - Toggle to remove the background and only show the grid and markings.

PATTERN SETTINGS

Pattern - Pattern selector from 1 to 6.

Grid scale - How big or small the grid is.

Grid subdivisions -  Number of subdivisions per grid unit.

Main grid thickness - Line thickness for the main grid lines

Secondary grid thickness - Line thickness for the subdivision grid lines.

Markings size - Size of the markings on the grid. Its effect varies from pattern to pattern according to the marking shape.

PATTERN 5 ONLY

Coverage - Percentage of grid squares that are covered
