      not in the same way as in sketchup shadow thea?

      You're mixing things up...
      Please remember that the hdri will also be a source of the illumination...

      Please take the advice Nigec have provided... πŸ˜‰

        If you want silhouette shadows is Thea, using frontal projection is the way to do it. But if simple "attaching" a model on a HDRI is enough then using shadow catcher is must.

          No you don't use a shadow catcher at all, it uses the actual geometry with a texture
          here's a SU version
          Su file

          you can also add bump, and reflections, but you need to use masks

                    Sorry - but after almost two years, I don't have that scene any more... 😐
                    What exactly is it you want to learn...?
                    How to setup a scene in SU with a shadow catching material...?
                    Or...?!?

                    Cheers

                        Attached please find a very simple model with some spheres...
                        THe render was complete in 16 seconds using the BSD preset...

                        I've used the "Harbor 3" hdri from the HDRI Hub IBL package, which is free to download for registered users... πŸ˜‰

                        Hope this can help you further...?!?
