SimpleBake is the definitive baking solution for Blender. In short, it allows you to simply bake PBR and other textures.  Blender provides a very powerful way to create complex PBR materials by using nodes. However, what should be a simple process of baking and exporting these materials for use with other software or systems (Substance Painter, Second Life, Sketchfab, Unity etc.) is surprisingly difficult.  SimpleBake aims to address this problem. SimpleBake is an addon / tool that provides a one-click solution for simply baking PBR maps from materials created in Blender.  However, SimpleBake isn't just an add-on for PBR. You can easily bake all of the "traditional" Cycles bake modes, along with other kinds of specialist maps (Ambient Occlusion, Curvature, Thickness, Vertex Colours and Colour ID).
