Magic of Lies

Material Layer Blend - a principle for combining material layers that creates a lightweight, quickly tunable system for blending surface effects - whether paint, dirt, rust, or scratches layered on top of one another. Control comes down to simple, clear parameters that set the order and intensity of each layer and decide which layer will dominate in the blend. Beyond texture blend patterns and channel selection, we added fine-grained control via inversion and per-pixel math operations. Reusing the same texture patterns also improves performance - reducing memory usage and simplifying streaming. Layered materials also make it possible to apply external, dynamic weather and other physical effects to a surface.
