OK, this is very strange.
If I pan the camera to just the 'wrong' angle, my image is blurry, but if I pan it left just a little, it's sharp.
I've uploaded a photo. This is the same exact camera, render node, settings, etc.
This is from the IPR, but it renders out to file the same way.
In the left clear image, the camera was 'panned' left of the fuzzy image.
What's going on here?
[update: I played around with it some more, and if I move the camera so the image is either on the LH or RH side of the screen, it gets blurry. So then I started playing with the camera settings, and when I changed the F-Stop to 22, it fixed the issue.]
