While I am adding a few posts on texturing I couldn’t leave out this recent tutorial regarding texturing an asset within Allegorithmic’s Substance Designer. The instructor is Christophe Desse, Environment / Technical Artist working with Naughty Dog (can you tell I am a fan!!!).
This presentation is packed with useful information on material blending, node creation and graph assembly whilst working with all PBR maps in a simultaneous workflow.
Christophe has further videos showcasing his workflow in Substance Designer and well worth a trip to his YouTube page.
