The model is included in a simple studio set up and it is ready to be rendered with Cycles. Diffuse map, normal map, and specular map are included. Some shaders use SSS for more accurate render. If you don't need SSS, just set the fac to zero in the mix shader node. To import the model into your scenes, just go on Menu File/Append or Link Object and choose the folder where the Cupcake was saved, choose the file, there you choose Group and Cupcake.
