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 bar. To apply this texture as a texture map, see Map a 2D or 3D texture.
