ezdz Posted October 26, 2009 Share Posted October 26, 2009 Is there a way to create a point cloud based on a PBR render? Basically I want to render a single frame with PBR to get all the bounced light, etc., then look up that point cloud when rendering multiple frames so I don't need to recalculate the PBR.

negow Posted October 26, 2009 Share Posted October 26, 2009 Would also like to know the answer to that. Out of curiousity, how would baking a point cloud differ from baking a photon map? I could probably guess the answer, but I'd like to hear it from someone else Quote Link to comment Share on other sites More sharing options...
DanBode Posted October 26, 2009 Share Posted October 26, 2009 Brian's path-caching asset in this thread might lead you in the right direction. Hope it helps, Dan Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted October 26, 2009 Share Posted October 26, 2009 The PBR photon map can be used again without having to convert it to anything else. Use one Mantra driver to create the cache with the Rendering Engine set to Photon Map Generation and then use another Mantra driver set to Physically Based Rendering (and set both to use the same map on PBR tab). The help has more information about caching and PBR rendering in the PBR section of the help. I remember seeing somewhere a command line tool to convert the photon maps into something else, but it might lose some information since its intended just to visualize the map. Cheers!

Even if I create a photon map I still have to calculate final gather per-frame, as far as I can tell. I'm looking for a way to cache all the data to a point cloud, including final gather.
