Possibly nuke lens distortion is not designed for such a ultra wide fisheye.
I also noticed Nuke's 3d card Lens distortion tab is deforming the vertices the card in a "planar" manner. The vertices and faces are not distorting in 3d space and is overlapping . Don't know if this explains the corner problems On Wed, Aug 14, 2013 at 2:33 AM, Randy Little <[email protected]>wrote: > to be clear I am only trying to distort (not re-distort) the cg to > match the undistorted plate.
