skyros Posted February 11, 2014 Share Posted February 11, 2014 Hello Everyone,I have an issue with a current scene I'm trying to break up into passes for comping. I have an avalanche that is flowing down a mountain side and only want the cast shadow to render. My setup is: - shadowmatte material on the mountain obj - vm matte is on for the pyro obj - shadowmasks on the lights are * ^mountain When I render a single image in the render view I'm left with an alpha of my cast shadow, as I would expect. When I export a sequence from my mantra output to disc I get no alpha. I've tried jpeg and tiff formats. Is there a setting that I'm missing somewhere? Thanks Mike Quote Link to comment Share on other sites More sharing options...
Guest tar Posted February 11, 2014 Share Posted February 11, 2014 Exr all the way! Shouldn't be any special settings for alpha. Quote Link to comment Share on other sites More sharing options...
