      Thank you, but it's not like I want to shadow

      Can you elaborate...?
      How do you want it to be...?

      Based on the hdri you've used, I think the shadow looks as it should...

      Cheers

          I'm not sure that your hdri has the best quality... 😐

          I can only encourage you to try this scene, where you can take learnings from the material settings etc...
          (NB! please note the file-size is 83Mb, because it also contain a free hdri...)

          With the scene you should be able to get a render similar to this if you're using the latest Thea4SU plugin...

              Tomasz used frontal projection with his scene
              quick tut:
              Setup you scene with the car on a plan add the hdri,
              scale the plane so it reaches the horizon
              Hide everything and render the scene, save the image
              unhide everything
              add the previously rendered image to the plane
              open the thea dialog and double click on the image
              set the diffused slot projection to frontal
              close the mat lab
              do a test render, you'll find the background is slightly darker, set the background intensity to about 1.7, you may need to fiddle about a bit
              thats it πŸ˜„

              Here's the Thea version as a pack file, I don't have the SU file on this laptop

                  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...?!?

                                    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...?!?
