Allegorithmic and NVIDIA will show how combining Substance, worldwide reference for procedural textures, MDL, the new standard to define multi-layer materials, and NVIDIA Iray, GPU-accelerated unbiased raytracer, will help solving artists and developers PBR material challenges from edition to final frame rendering for artistic shots. After explaining MDL basics and the associated material workflow in Substance Designer, we will showcase the latest edition of Substance Painter, market's most innovative real-time 3D painting software. Now embedding Iray as alternate viewport, Substance Painter fully leverages the power of MDL and Substance and natively enhances your art with the most advanced rendering quality reduced to minimal compute time thanks to GPU acceleration. Sbastien Deguy (ALLEGORITHMIC CEO) and NVIDIA will be showing with actual game artist content, how you can now iterate and render an infinite number of photo-shoot of your 3D art with one single tool.
