Sweet Home Season 2 | Netflix Original
This is a breakdown video for the Netflix Original project "Sweet Home Season 2". This project presented various challenges, raising the difficulty significantly.
The main issues include:
1. Zoom and anamorphic lens Issues
2. Matching Scene Scale without survey data
3. Matching the movement of the plates while characters and rigging mismatch
- Accurately matching the abdomen part of the character Yi-Kyung
- Challenges in matching the movement in scenes where Hyun Soo's body is attacked by tentacles due to the absence of finger controllers and significant differences in matching data
4. Rotomation for the underwater scene without survey data
"Sweet Home Season 2" project utilized both regular lenses (spherical lens) and anamorphic lenses. As you may know, anamorphic lenses typically pose challenges in distortion control and require significant working hours.
How We Overcame Challenges:
Car Action Scene:
Frequent use of zoom lenses with poor visibility of the background in car action scenes posed challenges. We had to employ various methods to create cameras to solve shots, using the car survey data. Additionally, there were numerous shots in the car action scenes that required object tracking. To ensure that these cars were properly attached to the ground, we needed to find the correct scene scale without survey.
Pregnant woman Yi-Kyung scene:
When matching Yi-Kyung's pregnant belly, we had to work with two types of rigging simultaneously: one with only the pregnant belly and another without the belly (since the modeling wasn't tailored precisely to her). We performed hand tracking using the regular rig, which included all parts of the human body, for the shadows cast on the belly, and matched the belly using a rig with only the pregnant belly. Generally, matching moves with curves are considered the most challenging tracking tasks. Ensuring that oval edge parts match perfectly regardless of the angle requires highly skilled techniques.Additionally, an improvised pregnancy belly prop was used to depict her pregnant abdomen. Because of this, each plate had varying shapes and positions, requiring meticulous attention to find the appropriate shape for rigging on each shot.
Hyun Soo Scene:
During the rotomation work where Hyun Soo's body is attacked by tentacles, there were many differences in shape between the rigging and the actual plate movement, and there were even situations where finger controllers didn't exist.When matching Sangwook’s arm attacking Hyun Soo, there was no modeling and rigging data that accurately surveyed his arm. Therefore, we had to create a mesh arbitrarily based on the plate and connect it to rigging to proceed with the work.
Underwater scene:
Since there was no survey data available for underwater scene, and all camera and roto animation work needed to be done, it was challenging to seamlessly integrate the two.
We anticipate that the segment around the 00:48 mark will captivate many viewers. Generally, when working on rotomation tasks, most artists use a method similar to the one that animation artists do, inserting individual keys while checking the visible parts manually. Instead, we employ 2.5D points in diverse ways. We anchor all elements within the shot to ensure that they adhere to the rigging, and create natural animation. This technique may pose challenges even for experienced matchmove artists. In essence, it involves re-rigging atop existing rigging, integrating with 2.5D points. Mastery of constraint functions and a profound grasp of 3D space (translation, rotation coordinates) are essential for this method. By utilizing this approach, rotomation performance is significantly enhanced, yielding high-quality results with minimal working hours, even for nuanced movements.
We selected shots for the portfolio based on our experience in overcoming these various challenges. Therefore, if you keep these aspects in mind while enjoying the portfolio, you will likely find it even more enjoyable.
