The Moire Mosaic texture node produces moire or mosaic patterns (figure 1).
Figure 1: The Moire Mosaic node and it's associated parameters
Shape - Determines the type of shape used for the pattern.
Size - Determines the size of the pattern shapes.
Corner Radius - Rounds the corners of the Frame shape.
Blur - Add a blur to the Circle and Ring shapes.
Shift - Applies a horizontal shift to alternating rows when using the rectangle and circle shapes.
Ring Spacing - Specifies the horizontal and vertical spacing when using the Ring and Frame shapes.
Iteration Count - Determines the number of iterations used by the shape generator.
Time - Provides an additional offset value when using the Ring and Frame shapes.
Transform Input - Positions, scales, and rotates the surface texture.
Projection Input - Sets how the texture projects onto the surface.
