- So in this video, we're going to start the process…of putting interactive lighting on these two pillars here.…Now, to do that, I'm going to need a mask…that will track beautifully to the pillars.…To do that, we can take advantage of the…camera tracking that we've done and use the…Solved Camera plus the Point Cloud Generator node…and create a Dense Point Cloud which we can use…to line up a card, which will contain the shapes,…which will track beautifully on the pillars.…If you do not have NUKEX, you cannot perform…the Point Cloud Generator steps in this video,…but you can use the results of it in the following video.…
So let's move our Center of Operations over here.…We'll bring the Viewer Node up to here,…and hook it up to the Grade node that we used…to color correct the shot to make it good for the tracker.…We want to use the exact same video…for the Point Cloud Generator tracking as we did…with the original scene.…Before I do the Point Cloud Generator, however,…I want to use a Lens Distortion node to flatten the scene.…
Each step of the process is rich in valuable production techniques, but is best for artists who are already familiar with NUKE. For more training on the basics, see Nuke X Essential Training.
