OpticalZDefocus

OpticalZDefocus is a physically accurate ZDefocus, which controls circle of confusion size based on lens geometry using the depth of field equation.

Set your focal length and film-back characteristics to match the lens that shot your plate
Animate your focus distance
Adjust the f-stop to match the size of your bokeh to your plate

How to mount a qcow2 disk image

This is a quick guide to mounting a qcow2 disk images on your host server. This is useful to reset passwords, edit files, or recover something without the virtual machine running.

Step 1 - Enable NBD on the Host

modprobe nbd max_part=8

	## Adjust size of all brush stokes in a layer
	## Expects a single layer in the rotopaint node containing strokes that want to be scaled.
	## This script scales the brushsize and source transform by the scale value

	_SCALE_ = 1.53706293

	rn = nuke.selectedNode()
	cKnob = rn["curves"]
	rootLayer = cKnob.rootLayer

Type in 3D point coordinates, or use vertex selection in 3D viewer and click set to pick average of selected points, or set points to set all four points at once. \n\nYou can connect node output to scene together with your pointcloud or geometry and see where your points are located in 3d space. Double click any of them to move it in 3d space like any traditional nuke transform control. \n\nA matrix transform is also generated to be used with RotoPaint, SplineWarp and GridWarp nodes. If you are using matrix in GridWarp, points have to be in clockwise order, pick them one by one! \n\nCommand set points doesn't respect selection order! \n\nCheck out the demo video on my website!
