Dynamic Grid Material

A grid material for blockouts that eliminates stretching through the use of world position. Uses Unreal Engine SM5 with exposed parameters. Includes parameters for primary (x and y-axes) and secondary (z-axis and gridlines) color as well as scaling (texture size in world-scale with unit multiplier) and MIP bias. Also uses standard PBR controls that default at 0 metallic, 0 specular, and 1 roughness.
