Week 17: Nuke Development

Green Screen work
Alpha

Using techniques I learned in class with multiple keyers, alongside make a hard matte, soft matte and transferring the alphas from these to a despilled version of the green screen. Though I still need to review how to make proper soft mattes as it is clear that I lost some info in the hair of the woman. The lighting as well doesn’t match up as the strong orange light in her hair doesn’t mach with the scene.

For our ongoing project I decided to try implementing a 3D object that I had previously made in the course into the scene to try my hand in 3D object implementation. One of the biggest struggles with it was adding a shadow to the scene as I had originally tried a few different ways that resulted in issues with the merging. Namely it would ‘double’ up the floor making a square piece of it, that was a card that the shadow was projected onto , to be significantly darker than the rest of the scene.

Though after examining another script that was sent to us by our instructor I was quickly able to fix that issue. I also brought in a 3Dtracker from a previous version of the file to use that to generate the cards I would project the surfaces onto which did fix some of my issues when it came to objects moving around in the scene when they should be totally still.


Again issues exist with my current roto but I still lack the time to dedicate to fixing it.
