I love love love the new Depth of Field option in the viewport, I've got lots of ideas for how to use it... but already I'm seeing some problem. In particular; here's one of my old scenes I'm trying to apply DoF to:
The "autofocus" feature means that any time you move the camera, or even when the scene loads up, the focus is on the wall in the background, not the sword-in-the-stone in the foreground. It would be really nice to have an option in the 3D Settings to lock the focus to a certain object in the scene. For scenes like this, or dioramas, etc... it would allow the creator to make sure that the focus isn't constantly jumping around creating undesirable results.
Perhaps just an option to disable the autofocus by default might work, so people can set the fixed distance they want the focus, and then when users tap to change the focus it stays in place rather than jumping around- even give the users the option to turn on/off autofocus in the viewer settings.
I think there's a few things that could be done to really improve the results, because I love the effect, the implementation just feel a little bit clunky at the moment.
