In the Materials folder (All Materials>3D>Body type). Click in 'paste material' and it will appear in your canvas. The face isn't a default model though, you have to download it.
As I understand correctly CSP is a paid proprietary software, isn't it? I am still in search of a good but preferably free software or website that might provide a 3D model to manipulate to draw poses. Do you know of any service like that? Thanks.
