Maya 2018 | Arnold 5
- In the camera shape node’s Arnold Attributes:
Check ‘Enable DOF’.
- Set ‘Aperture Size’ and ‘Focus Distance’ to control the effect.
The Aperture Size attribute isn’t an f-number aperture like we would expect in photography but a radius in world units.
Larger Aperture Size values (larger lens Iris opening), and shorter Focus Distances will cause a narrower Depth of Field which will result in the background appearing more blurry.
DOF is generally more apparent with ‘long lenses’ (shorter focal length).
- Set other Aperture attributes like the number of blades and aspect ration to further design the appearance of out of focus areas and especially highlights.
* The optical effect referred by the term ‘Bokeh’ in photography.
