向補習說再見

In this course we?ll learn how to create a 3d sky using a pan and tile

technique in NUKE. By stitching together multiple photographs, we will

be able to create a fake sky background for our composite.



We?ll begin this project by learning about the card node in NUKE, and

setting up the card to correctly have lens distortion, fit our lens,

and set-up the initial node networks for faster duplication. We'll

then connect the rest of our sky cards and use some math to make a

rough placement. From there, we' ll refine the rotations and placement

to hide as much of the seams as possible. We'll then tie all the cards

together into an axis so we can control the entire sky using a single

transform. After that, we'll match our sun placement, color correct

our sky and render it separately to use z-blending to hide our seams.

Finally, we'll learn how to fix issues with our tiles using NUKE and

Photoshop, then do a few final compositing tricks and render our sky

sequence.
