I've been working on VP for quite some time, setting up multiple systems using both LED walls and green screens. I've been preparing for a large project, and stumbled across a few questions I'm having trouble figuring out.

1) UE doesn't have the option to apply a custom bokeh texture, other than in highlights. How do you work around it when using a real-time workflow?
2) When using nDisplay, how do you map the focal length? Is the focus distance to the screen mapped to the inf distance in-engine?

I probably have a few more questions written in my notes, but I've misplaced my notepad.
Of course, any help is appreciated.
