Week 3

Week three has been pretty eventful, from reshooting, to a hurricane, progress was slow, but I still managed to get a good chunk of work done. One of the big changes this week is the decision for Min and myself to split the shots down the middle. She’ll be working on shots 3-4 and I’ll be working on shot 5. My shot is inside the freezer with the ingredients filling up the container. Initially I tried to simulate the ingredients using RBDs and FLIP, but I realized that trying to fill the jar made it really difficult to direct and iterate, and I ended up with some pretty gross simulations (see figure 1.). I also tried mpm for this purpose with mixed results. So I was stuck for a while not sure where to go from there, then it hit me like a brick. I just needed to do everything in reverse, so instead of trying to simulate the ingredients into the jar, I just needed to simulate the ingredients leaving the jar. Which lead me to my current workflow

WORKFLOW

I started by making a cylinder that fit into the jar, and then cut the cylinder into sections using a grid affected by a mountain node, and a boolean. I’ll be revisiting this to make it look more natural.

Next I separated each “ingredient“ into its own path using a blast node

After this I set up for my simulation (note that the same process was repeated for all “ingredients“) I first turned my geometry into a flip dop source, ran it through my simulation.

I kept the simulation very simple for now, to make it easy to modify and iterate

I have a simple pop curve force, and a pop force thats adding turbulence

Then I just move it into the fridge asset and do some basic lighting and shaders, and then hand it off to Gracie to shade and light.
