Differences between this 2 models The model (01) the ground is connected to the model (see chapter 04). Recommend for CS4 or CS5, if you want to set floor reflection or place a texture map. The model (02) render ground plane shadows in a transparent background. To activate you must go to the top menu in photoshop select 3D them activate Ground plane shadow catcher and them Snap object to the ground plane before render, recommend for CS6 and above, that have better controls, like merging several models in the same layer to cast shadows and share reflections... (Only in CS6)
