The nice people over at Allegorithmic recently invited me to try out Substance Designer 6 in beta; this is what I have to show for my time with it.
A Substance for generating a Gothic Rose window bedecked with Roses. The graph could now quite feasibly be modified to generate variations of the architectural elements, then used to create a whole texture set.
I made a lot of use of the new Curves node which proved invaluable for creating the carved masonry. A lot of the shapes I made with the Curves node would have been practically impossible with simple gradient adjustments, or at the very least a lot slower to perfect. The text node made adding flavour with the inscription a breeze.
Apart from an imported bitmap for the Substance "S", everything was created entirely inside Substance Designer 6.
