Bulge

Procedurally creates a grid of white squares that fade to gray toward the edges. Use as a bump or displacement map to create surface bulges, as a transparency map or specular map to simulate real-world objects, such as windows that are dirty around the edges, or as a color map to simulate tiles.

Find this texture in the Create tab. To apply this texture as a texture map, see Map a 2D or 3D texture.

Uwidth, Vwidth

The width of the texture squares in U and V directions. The range is 0 to 1. The default value is 0.1.
