To-do:
Balance the background between all shots
Wood grain direction and emphasize the bump/normal map more
Shot 4 lighting is too flat
Add a fill light to shot 3 inside the printer before particles come in
This week, we are focusing on small finishing touches before we meet the mentors in person to show off our final video. The main focus is to maintain consistency between each of the shots. To do that, the background in our final shot must be updated to the backdrop that is seen in all of the other shots. There are still some lighting issues to address in shot 3: the beginning of the shot is too dark before the emissive printer particles appear. The lighting in shot 4 is too flat, and we want to add colored lights to make the shot more visually similar to shot 1. I also want to make some small updates to the wood material within the shader, such as bringing the variation between the high and low bump values closer together.
Rendering needs to begin on Thursday this week to allow as much time as possible for our compositor to work. This only gave my team and me Tuesday afternoon to Thursday morning to make all adjustments. I began with the background, as that was the most obvious and pressing change. The background needed to be updated in shot 4, so while I worked on that file, I also updated the lighting slightly. I changed the position of the fill light that was at the front of the printer and lowered the exposure and intensity of the key light. I added some lights to point directly at the backdrop since it was picking up light differently than the previous background. Next, I worked on adding some more light at the beginning of shot 3. This was a bit of a challenge for a variety of reasons. First, the viewer was glitching in a way that the position of the light would not hold when switching from the Houdini VK viewer to the Karma XPU render view. This issue was not resolved, so we had to work around it. It would take multiple tries of placing a light before it would finally "stick". Second, I tried placing a new fill light in multiple places in the scene, and each placement either had an odd shadow on the printer or a distracting shadow on the background. I tried turning shadows off, but then the scene would get too flat. We ended up adding a whole new key and fill setup onto the printer just for the first half of the shot, then keyframing the intensity down to zero when the macro shot begins. This avoids the lighting from having distracting shadows or looking too bright. I also updated the range of values for the bump map and added a color correction to the wood material while working on this shot.
