This started when I applied an ease to a position key frame on one of the layers. I have no clue how that could have caused this but I still cant get my depth back.
I did add a 2d layer at one point but that was made 3d immediately. I mean, I made it a 3d layer immediately to make it work it within the other layers.
When I put in a new camera and start completely from scratch, none of my setting modifications have any effects on the depth of field. Everything stays flat.
I tried all of this and nothing fixes the problem. It has to be some other setting that toggles the depth of field on and off or a pita bug. Nothing makes sense.
