Robbie McC Posted August 19, 2019 Share Posted August 19, 2019 Is there a way to create an infinite background? I am modelling product displays and would like to be able to place them on an infinite backdrop so that I can have reflections and shadow on the floor and a clean background. Cheers!

Kevin Allen Posted August 19, 2019 Share Posted August 19, 2019 When I want this effect, I create a large cyc (or cyclorama) for the background, generally black or white with a certain amount fo gloss. Not rue black or white, but a light or very dark gray. Cyc is generally and entertainment specific term, but I have a solid that consists of two walls and a floor. The corner (between the walls and between the walls and floor) are 'coves' like a cove moulding, just a sweep. 1 Quote Link to comment
Robbie McC Posted August 20, 2019 Author Share Posted August 20, 2019 Thanks Kevin. Do you add the solids or do you keep them as single objects. I have tried something similar - as one solid - but can never get a true seamless look. (This may due to bad lighting though. Secondly approx what kind of radius do you have for the cove?

Popular Post Andy Broomell Posted August 20, 2019 Popular Post Share Posted August 20, 2019 Here's one approach, though I'm not 100% sure what you're going for: -Model your object. -Don't model any geometry for the infinite background. -Render in a sheet layer viewport. -Set RW background to None (if you want transparency upon export), or HDRI white would work too if you don't need transparency. -Where you want shadows/reflection, extrude a circle or rectangle to 0", and make/apply a shadow catcher material. This will give you the shadows and reflections, but no rendered geometry. (One drawback is that shadow catcher reflections apparently don't have a blurriness parameter). -Use File<Export<Export Image file if you want to be able to export a PNG with transparency.

Popular Post Kevin McAllister Posted August 20, 2019 Popular Post Share Posted August 20, 2019 I'd love an infinite floor object, especially if it was made to work with the horizon of a Renderworks background.... Kevin 5 Quote Link to comment
Robbie McC Posted August 21, 2019 Author Share Posted August 21, 2019 Thanks a lot for your help guys. I'll experiment with both and let you know how I get on! Quote Link to comment
DaveBB Posted June 11, 2020 Share Posted June 11, 2020 Andy. Missing a step here. How do you apply a 'shadow catcher' object. I went through the link you included and the video link from that help page. They all describe the shadow catcher quite well, but never mention specifically how to create it. Quote Link to comment
Andy Broomell Posted June 11, 2020 Share Posted June 11, 2020 (edited) Shadow Catcher refers to a type of texture; it can be applied to any object. In my example above, I drew a large circle and extruded it to a height of 0", then applied the texture in the Render tab of the Object Info Palette.
