    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˜‰

        Cheers

          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...?!?
