Winners of Allegorithmic’s latest contest
Allegorithmic announces the winners of the latest Substance Designer contest and gives honorable mentions to runners up
The winners of Allegorithmic’s latest contest have been announced
For the materialize contest, entrants chose an image from Allegorithmic’s mattershots instagram account as a reference and then proceeded to create the material using substance Designer. “Judging work of other people is never easy and picking them among dozens of excellent work is even harder. in the end, i had to be very strict on my criteria to get my final list – the devil is definitely in the details!” says nicolas wirrmann, substance Designer product manager at Allegorithmic.
First prize in the MDL category was awarded to mark Foreman’s malachite material. “i chose to enter without having more than dabbled in the MDL side of substance Designer,” says Foreman. “i wanted to mimic the natural stone flow and do the utmost in a single node string to drive the cut and uncut malachite surface. the front half of the graph mostly generates the surface with its Chrysocolla layer, starting with large nodules that would form cut peaks. on top, i layered small and medium shapes and surface noises.
“then i performed a slice based on a height value at the graph midpoint to create the cut surface. Changes made to the first half automatically reflected in the cut malachite surfaces without individually managing separate node strings. Height map work beyond this added minor splits in the rings and radial cracks.
“i then created maps to drive features in the MDL for the cut surface starting with a simple rough/spec graph before adding more complex features like an anisotropic direction map for the cut surface highlights, and masks for the two separate surface treatments.”
For technical mastery winner Quentin marmier, the hand-crafted nature of the metal engraving meant that it was the most challenging to reproduce. “i kept patterns as procedural as possible, especially for the hand-drawn figures, and used svgs for final details (the head and bigger flowers use SVG nodes on which i copied the original design pattern). i then added imperfections to lose the CG feel. the dragon body is made up of regular shapes and the Cartesiantopolar node for bending. using my coding and nuke experience, i created custom nodes to get readable parameters for drawing shapes with the dragon body while keeping control

of the details. i also modified the Cartesiantopolar node for anti-aliased, finer results.
“the little flowers use customised tile sample nodes for specific parameters related to the engraved figure. the logo uses regular composed shapes in a single element, enabling placement and duplication. i created independent substances to produce the engraving, logo, dragon body, metal and wood; doing the final assembly as a master substance enables independent changes or the ability to inject different shapes where patterns would be. i also created a custom remapping node for the layered look of veins in the rosewood. Finally, the different material noises are driven by a main ‘dirtyness’ attribute.”
Gil Damoiseaux’s Givenchy fabric entry received an honourable mention. He explained, “the biggest challenge was re-creating the fabric itself as it has a lot of subtleties – mainly in the colours, but also on the relief. i spent some time collecting reference pictures, especially very high-definition ones, to correctly understand the underlying structure of the fabric, and also because the reference picture was quite low definition.
“Finally, i made some photos of similar clothes i have to help me out. the fabric itself is a quite repetitive pattern and this was something i’ve tried to break in the final material. Fortunately, at that time, Allegorithmic added a feature that made my day – the flood fill node. Combined with the flood fill, the random colour helps me adding colour variation along the yarn quite easily.”
