Hi,

Looking for most elegant/preferred way to approach adding overscan to allow for lens distortion in post.

Render settings offers "Data Window NDC" and rollover help suggests using this, so I dial in (-0.05,-0.05,1.05,1.05)

Reading into nuke and the bounds are expanded as I'd expect, but the picture is scaled up by the same. So feels like I'm missing the "Screen Window Size" setting to adjust that back. I can modify the camera's aperture to correct. Doesn't feel like the right way to do it.

How are people doing this? Ideally this is would work for any delegate...

Check out the tutorial "A Beautiful Game" Part 10 deals with overscan setup (and the caveats) for Karma.
