When I opened the coffee source blend file and hit render to make the before picture, all I get is a bright pink, which means a texture is missing. When I went into 3D view to check, it shows that the Blender scene is completely empty, nothing there at all. Can you please check the source file to make sure it is good. Or is there something I am missing to make the connection to the .esr file possibly?
The Compositor Nodes look a little different and I had to do some researching but I finally found out how to set up the render passes.
