If I did mixed media today...
I stumbled across two After Effects plugins this week that allow you to do some AWESOME mixed media integration amongst other thangs...
Normality
Render out a normal pass with your 3d scene and use this plugin in AE to relight the 3d geometry...yeh ya heard me right its pretty suite... Can do some insane 3d/stopmo/2d or 3d/live action with this thang...
Youveelizer
Render out a UV pass with your 3d renders and use this plugin to retexture the 3d objects in After Effects...you can add reflections and other thangs to help compositing of 3d in other media as well...
Pretty win stuff if ya ask meH. Mix that media maynE!Brought to you by professional weirdo M dot Strange.
