Depth of Field II: Vengeance

[Beardyfella]

Ok guys. I'm still havgin an awful lot of problems with DOF. Now it seems that it simply doesn't work at all.

Here're some images:




My model units are meters but i tried using all units known by mankind on the DOF override focal distance with no success. On the images you can see i tried setting an obscene distance just to check if the thing was on, but it appeared to be completely off.

I have experienced unstable behaviour previously, when DOF seemed to adopt the scene units for some files and strict inches for others. I'm not quite sure how to operate this thing now. :-\

I think your F-Stop is too small.


As for the units - Sketchup internal units are Inches. You have to specify units in VfSU in inches no matter what your model units are set to.

Re: Depth of Field II: Vengeance

A small f-stop would only generate an overblurred image, not the oposite.

And i thought that was correct too, but i recently found evidences that point otherwise.

Look at these images carefully as the only difference between them is the unit change on SketchUp itself.
Inches:
Feet:
Centimeters:
Meters:

Looks like it does change with the scene unit, but it doesn't follow it exactly. Any thoughts on this?

Edit: After some tests, i've discovered that the DOF works with meters and feet, but it only blurs out the things that are beyond the sharp area, not the ones that stand nearer to the camera.
