Red Light, Green Light: Enhanced Set Design and Execution

The initial phase of our project involved aligning the visual effects (VFX) of Squid Game: The Challenge (SGTC) with the original drama. A notable aspect of the drama was its reliance on green screen and blue screen techniques for set extensions, particularly for the walls and sky. However, our project benefitted from the construction of a substantial physical set, measuring 100m x 40m, including full-height walls and a 13m tall doll structure.

The set underwent detailed photogrammetry and drone scanning, which facilitated the following VFX enhancements:

1. Extension of all walls to their full height.

2. Creation of a sky backdrop that matched the existing lighting conditions.

3. Removal of camera windows from the end wall.

Certain concepts were explored but later deemed unfeasible, such as keeping eliminated players in their fallen positions (due to the extensive camera work involved) and real-time wall extension for wide camera angles.

The VFX process underwent several developmental stages before finalizing the look presented in the show. Pre-production assumptions included the need for extending wide shots from various angles and adding extensions to drone footage, which required meticulous match moving. Additionally, some camera positions necessitated partial wall extensions.

Glass Bridge: Creating Realism within Constraints

The Glass Bridge segment posed unique challenges. Similar to the drama, the original set extensively used blue screen and green screen for extensions. However, our approach differed due to the live nature of the competition, budget limitations, and time constraints. Unlike the scripted drama with a limited number of cameras, the unscripted format of SGTC required managing footage from over 20 cameras simultaneously.

The objectives for the Glass Bridge segment were as follows:

1. Convey the illusion of the bridge being suspended 50 meters above the ground.

2. Initiate the game with a continuous shot (oner) starting from the bottom of the pit to the entrance of the contestants.

For safety and realism, the project also ventured into the realm of facial and head replacement, a complex process detailed in an accompanying document.

This whitepaper provides a comprehensive overview of the VFX strategies and implementations employed in SGTC, showcasing the intricate balance between creativity, technological innovation, and practical constraints.
