I'm trying to create this effect and it seems no matter what I do, nothing is working.
I have 3 text layers, all 3 have the 3D enabled and are spaced out in Z space. Draft 3D is turned off. I'm using a 35mm one-node camera, Depth of Field turned on and an aperture value of 97. Preview is in all full quality resolution. No matter where I move the camera or the focus distance or the text, everything remains in focus.
Can anyone offer any insight into what I might be doing wrong?
Not without a screenshot... DOF enabled? 3D layers? Aperture set? Other effects or layer styles applied to your 3D layers? All can have an effect. Show us your composition.
