To-Do for Week 4:

  • USD optimization

  • Ivy simulation movement (vellum incorporation)

  • Correcting ferns

  • Adjusting FX to blend with Yiyi's layout seamlessly

Here is the most recent previz. Some of the suggestions from our professors still need addressed, but we:

  • Prioritized Shot01, adding more filler objects.

  • Included the vine in shot02. I plan on incorporating it into shot04 as well in the near future

  • The headset does not intersect the table anymore.

  • Slowed down shot04 abrupt camera (still needing improvement).

My group quickly compiled our assets together for Saturday's review. We changed a lot of things around story wise and we want our intentions for the new previz well-defined and clear.

Professor Feedback:

  • Shot01 layout needs refined & should be the biggest priority

  • Shaders on flowers need included

  • Include the vine into more of the story if it's going to 'lead' the progression of the commercial

  • Shot04 & Shot 05 headset is intersecting table

  • Shot04 camera ends abruptly

  • Communicate CG/Live Action plan

  • Show lighting references or completed lighting charts

The ivy simulation is my biggest priority for this week. I want to get a general idea of its location and growing points.


Shots 01 & 02 are planned to have animated ivy. Simple Tree Tools gives me a clean way to efficiently lay down branches along any surface in my scene.

Ivy Growth Test
Ivy Branch layout for Shot02
Ivy Bounce for Shot02

What I want to fix:

  • The "bounce" needs to be softer

  • The growth is too fast

  • The placement needs changed around

I'm quickly running into exporting problems with my simulations. Simulations like the vines or ferns are causing USD crashes in OBJ level. I've been discussing with Professor Fowler for a possible solution, and it looks like my animated geometry is too dense.

As much as it doesn't seem like a lot, the way it's animating based on bone deform rules are causing major hiccups in my deliveries. Most of the attributes listed do play an important role with growing the vines, but I can surely find a way to optimize them.


I plan on fixing my simulations and finding an efficient way to export them for my team!


As of right now, it seems best to export multiple USDs for every animation sequence. The scene wouldn't be as heavy with one large USD. I'm still juggling different solutions around.
