    I´ve tried to set camera focal lenght the same as in photomatch - 25mm but without any success. If I use physycal camera there is only worst scene lighting..

    There is a link to packed scene: http://leteckaposta.cz/822737484

    you might try selecting the zoom tool in SU, and then exactly re-type the view angle in the text box at the bottom right of the screen. This can reset any distortion in the photomatch view, allowing vray to render the same angle as the scene view.

      no, don't adjust the vray settings (please un-check the FOV override.) This is in the SU vcb (in the bottom left of your screenshot.) Just re-type the number "25" and the view will jump out of photomatch, but should retain the same perspective.

          Does it match if you scale it to the proper size relative to the photo - if you overlay it in Photoshop?

            no - to match it I had to change camera setting to physycal and zoom factor to 1,40.
            Output is almost correct but the way how to achieve doesn´t..

              Hi
              even if my comment dosn´t help you further in your matter, your customer will have a new kitchen as well!
              Separated from this strange camera bug, your work is good really. To do such an interior simulation is more difficult than an exterior. The post pro transition between photo and VR is very well done!
              👍

              never trust a skinny cook

                  Let me clarify a bit. Re-typing the field of view and jumping out of photo match will make sure that your view is not distorted and that vray can render at the same viewpoint. The size of the image will not be an exact match, you will either have to adjust it in photoshop (which I did here) or by trying to get the height and with of the render to match your photo. Note that using degrees instead of lens length will get you a more accurate match (this is 71.31 degrees in this view for example. The 25mm is not as accurate.) I can send you the photoshop file if you want to see what I did to get this view.
                  Hope that explains it a bit better.

                    Hello Andy, thank you. I tried it now.
                    So at the moment I do not have a problem to have the same view (which is not distorted) as matched - I can do this by Reset camera aspect ratio - as attached.
                    I can render this view - without bg it looks good.
                    When I use enviroment background when render, model is moved to different place/size so doesn´t match with background. (in matched scene is the top of the TV wall at the bottom level of lighting,)
                    Could this be solved to I can render with background also (background is the same picture as matched photo, the same size as I want to render)?
                    BTW how can I switch "mm" to "degrees"? Thank you

                    original - model matched


                    reset camera - only model


                    model rendered but doesn´t match with matched picture/enviroment background

                      Please does anyone knows how to render it corectly?
                      Similar problem (without enviroment background was in the post http://sketchucation.com/forums/viewtopic.php?f=322%26amp;t=43350 )

                      When doesn´t match enviroment background on the screen with render output, I can´t save image with wrong hdri lighting and whole work is useless... 😞

                      I have an idea - could be the problem in enviroment setting?
