squardis Posted September 20, 2016 Share Posted September 20, 2016 I have searched for along time now, Im trying to search for a way to render a shadow without any compositing applied and see the Lighting geometry of my hdri in the background. Is that possible? like arnold / vray etc. thnx example scene: sphere object / hdri / grid as shadow Quote Link to comment Share on other sites More sharing options...
davpe Posted September 20, 2016 Share Posted September 20, 2016 what about Shadow Matte material preset and enable rendering the background image? doesn't that doing what you want? Quote Link to comment Share on other sites More sharing options...
squardis Posted September 21, 2016 Author Share Posted September 21, 2016 Well, the background image is a HDRI so it looks weird to see the full latlong image. Render light geometry on the enviroment does what i need but it makes the shadow matte material black. The shadow matte seems to work in alpha but in de RGB i get a black grid With background image turned on you also cant orbit around like in the enviroment light shadow matte.hip Quote Link to comment Share on other sites More sharing options...

(I think) If you need to match the shadows / with a backplate you would like to be interactive and see the changes directly. rendering out render passes is a second task. So there isnt any way to do in mantra like Vray or Arnold can? Expand Quote Link to comment Share on other sites More sharing options...
