How to Use Grid Texture in Maya
The Grid texture can be added to any of the surface material's channels. It can be used as a grayscale or color pattern.
Open a scene with a polygon plane primitive. Right click the object and choose Assign New Material > Lambert. We will build a wall with windows for an office building.
The new Lambert texture panel opens in the Attribute Editor. Click the checker-box next to the Color slider.
In the Create Render Node - 2D section, right-click the Grid icon and choose Create Texture. This creates a Grid texture that is UV mapped to the object.
In the Grid options set the the Filler Color to medium gray (windows). Change the U Width to 0.200 and the V Width to 0.400.
Click the Presets button and select Save Grid Preset. Name the grid in the dialog box.
Returning to the main shader dialog box, click the checker-box for Bump Mapping.
Right-click the Grid icon in the Create Render Node panel and choose Create Texture. This creates a Grid texture that is UV mapped to the object. In the Attribute Editor click the right arrow next to Bump Value in the bump2d tab.
In the Grid tab, click the Preset button and replace the grid with the one you saved. By using the preset, the color and bump information are aligned. Render your image. You now have a window panel with a very low poly count.
