This is Toudou. I have recently released e-book titled "Substance Painter for Blender Users".
This book explains effectively how to use Substance Painter, what we need for collaboration between Blender and the Substance Painter and how to use textures created by the Substance Painter in the Blender.
You can learn how to use the Substance Painter smoothly. Also, you can see a series of movies of workflow from modeling, exporting object data from the Blender, creating textures in the Substance Painter, using the textures in Blender and rendering with Cycles engine.
