loopyllama Posted September 28, 2013 Share Posted September 28, 2013 Hi, I am struggling with this. Maybe someone knows the answer? I'd like to have a extra deep raster image in my .exr render that is a matte pass for my scene. My scene has some sops and a few VDBs. I'd like to add an attribute with unique values to my objects and the VDBs. I'd like to render this value in my deep raster to use as a matte pass. I would separate out each color in post to use an mattes. It would be easiest if the attribute was a color vector. Is it possible to add a vector attribute to a VDB and render it in a deep raster? How would I go about doing this? Quote Link to comment Share on other sites More sharing options...
substep Posted September 28, 2013 Share Posted September 28, 2013 (edited) Deep camera maps (DCM's) alleviate the need for rendering out extra mattes/holdouts. Maybe that will help you instead...?

substep Posted September 28, 2013 Share Posted September 28, 2013 np, deep compositing is really useful. Nuke makes it super easy, and has some additional tools for working with deep data. a 20 minute tutorial and your set. goodluck! Quote Link to comment Share on other sites More sharing options...
