Esko Studio

[OrigamiEstudio]

Has anyone tried out Esko Studio + keyshot? Do you see that is worth it to buy it in terms of quality of rendering and time saving (because they have a library of standard packaging as I can see)? Any complaints about the software? Any limitations with the 3D modelling tools? Are complex 3d models (like conceptual packaging design) feasible within the Esko Studio?
Cheers!
