Team Discussion:
Shot 3 is the hero shot - main priority
Shot 1 is the subhero shot
Getting rid of shot 4 live action. Getting rid of shot 5 completely.
Completed:
New comp with new renders
Depth of Field issue (lack of information in render) figured out
To do:
Set up ID AOV in Houdini
Set up render layers
Improve glow and add variation on plant and vines
Continue refining color - currently too dark
This week, the team had many big discussions on how we want to move forward with the project. We came to the conclusion that shot 4 was really heavy (live action, live action interaction with CG, disintegration, lighting change) and realistically could not be done with the time we have left. Without all of that, there is no need for shot 5. Shot 4 will now serve as the product reveal and the ending title.
One of the biggest things I figured out this week was the depth of field issue I was having. The problem was the far clipping in the Houdini camera settings. It is automatically set to a really high number. Decreasing that to as low as possible resulted in the depth AOV having all the depth information.
default clipping adjusted clipping
Next thing I have to figure out is how to improve the edge quality of the objects in the foreground when the background is out of focus. I have a set up that partially works, but I need to keep adjusting it.
Right now, I am using the depth of field as a mask for the foreground, blurring the edges, and merging that on top.
By default, the zdefocus filter type is disc (fig.1). Changing it to image (fig.2) gives a masks of everything in focus.

original mask -> blurred -> merge over
It still needs work, but I'm also going to see if there is an easier way to fix the edges.
Another thing I need to figure out this week are render layers and how to properly set up an ID AOV. Out ID was empty because we didn't set it up properly. I think that AOV will really help me control the lighting variation on the couch throughout each shot. I would also like to create a fresnel material for the vine and possible render the vine separately so I can play with the relighting in Nuke and get a unique glow.
