• Catseye
• Barndoors (cropped bokeh in edges of image)
• Lens breathing based on the bokeh created (spherical/anamorphic lens)
• 2D defocus and depth based defocus
• Easy to use bokeh creation tool, with a default beautiful bokeh
• And many more

How to install

Copy/move the MagicTools folder into your .nuke installation. Then merge the contents of the init.py file with your init.py file (if you do not have one copy the file provided in the zip). Or add the following line to the existing init.py file:

How to use

It looks very similar to the default Defocus/ZDefocus node, but it has a lot of extra options. All the knobs have a help text when hovering over the knob.

User interface

1. The first tab contains all the main controls for the defocus. The size slider controls the main size of the defocus, as well as the max size when using depth defocus.
   To change to depth defocus, change the method knob to depth.

2. The second tab is the bokeh creation tool. If you click the preview filter knob, it will give a preview of the bokeh created with the settings. You can also use your own bokeh kernel. To use your own image: set the filter type to image. Lens breathing is linked to the aspect ratio knob in this tab. When using for example 0.5, the breathing will be anamorphic. A value of 1 will make the breathing spherical.
3. The third tab controls the non-uniform bokeh. Ticking the enable non-uniform checkbox will enable the other options. Hover over the knobs to see what everything exactly does!

Thanks

Special thanks to Chris Fryer who inspired me with his blogpost about cropping the image into slices, and for his excellent explanation of the amazing timeblur node.

Also thanks to everyone who took the time to look at the node, and gave me feedback!
