Adobe has released Substance 3D Painter 12.1, a major update that overhauls texture baking with continuous rebaking and skew correction painting to fix normal map errors directly on the model . It establishes OpenPBR as the new default shading standard for better material interchange, and adds a dedicated hard surface UV unwrapping mode for mechanical assets . The release also introduces edge protection, multi-channel editing, and a unified undo history to streamline complex texturing workflows.
