The auto-focus does not work for animations. You just added the 'delay'
feature in it to make it "work". Results of using that are highly
disapppointing in real testing situations. Try to use this in one of
your more serious projects!
All of this because it's not DoF, but a zbuffer blur based on splitting
zvalues in 2 halves, front/back, and use a two-pass filter to blur the
picture. Its use is limited to a full understanding of zbuffer values,
setting up correct camera clipping, a correct zmin value, and actually
a correction zmax should be added too. With a very painful tweak of all
settings you might get a nice looking picture, but with the "focus"
moving around during an animation the results will look just ugly.
Even *if* it were a good working zblur system, then still the focus
distance should just become an Ipo curve for a much more natural
I don't blame your work, but the quality of zblur itself... which is
just a very hard to handle post effect, and hardly useful in more
All good looking 3d animations I've seen with a DoF effect don't use a
straight single-picture zblur, but render a picture in multiple layers
(front part, back part, maybe center part). Then these parts are
individually blurred, with alpha, and composited again. Such an
approach belongs in our sequencer.
