Recently while working on an independent feature film, I was called upon to create a heaven type effect integrating green screen elements with a naturalistic painted feel. While researching techniques I stumbled across a Siggraph paper from years ago creating a stroke technique using motion blur, I adapted this idea to work in Maya by distorting objects in between frames with motion blur and sampling at a higher rate. This gives the look of the motion blur samples being frozen in time in 3D space, giving a 3D paintstroke feel. Having the green screen footage at Red 4k didn't hurt either.
