If you've played any AAA videogame in the last few years, chances are you've seen Allegorithmic's tech in action. Headed up by Sebastien Deguy, the company's Substance Painter and Substance Designer help artists create and fine-tune realistic textures which aren't repetitive or obviously procedurally generated.

In this podcast, recorded at the Vertex conference in London, Sebastien tells Chris how a single mistake lead to the founding of this fast-growing and innovative company, which is branching out into visual effects and architecture. He also talks about the little tricks Allegorithmic uses behind the scenes, the future of the software, and even how we can understand the universe through mathematics.
