Defocus strange behaviour
Hi guys!
Unfortunately I am not at home now, hence I don’t have a blender file for you. Not for now anyway.
Hopefully you can think of something from the information that follows:
I have tested the effect with a simple setup of just 4 cubes formed in a line, on a plane, a sun-lamp, and the camera. As expected, the camera is looking to all the cubes line, from one end.
Once I have the needed Compositing nodes in place (from left to right: Render layer, defocus, compositing, viewer), then I go to the camera settings in the Properties tab on the left (default), and with the droper choose the cube I want to apear clear, and adjust the… mmm I can’t recall the name of that setting now. Well, it worked with 0.0600. And if I put the Viewport display mode to “rendered”, then I’ll be able to see that things are working on the fly. I may need to do one initial render and keep that “Auto render” feature checked in the Compositing window (at the bottom).
Now, all that is nice and dandy, but when I replicate the very same with the scene where I really want the effect on, it just doesnt pan out the same. Instead the whole area I applied the border to (to select only a small portion of the whole to be rendered), gets blurred, and with too high a value no matter what values I enter.
The only time when I can get some control is if I enter the values for the “Distance” instead of using the dropper. The problem with that method is that no matter what distance values I try, I can never get the important element to appear clear enough.
So, based on the info above, I hope someone can sort of pin point something.
Later on in about 7 hours I will be able to upload a file.
Thanks guys
