Enter the Matrix Knob
A new feature in Nuke 6.1 is the exposed matrix knob on all 3D nodes that allow a transform (such as ReadGeo, Axis, Camera etc). This contains all the transformation data for the node in a 4x4 matrix expressed as homogenous coordinates.…
Dealing with NaN pixels
Here's an approach to dealing with the occasional NaN pixel that can for example crop up when outputting through the ScanlineRender node.…
