Traditional options do not allow for order-independent mixing and this node provides for easy mixing of multiple inputs if needed. Bump mapping is an inexpensive way to add small surface details through shading rather than modelling them. You can also chain these nodes together for more complex networks using masking to vary bump maps across surfaces while using a single material assignment.

Input Parameters

• Add Add - Add the results together, A + B

• Over - Puts A over B, a mask is useful here to reveal the layer underneath, A+B(1-a)

• Subtract - Subtract the results, A - B
