Girls’ Frontline 2 Devs Patented Rendering Method and Device

Commitment to Realistic Silk Stocking Rendering

MICA Team/Sunborn has officially patented their innovative method and device for rendering silk stockings in games. The patent was filed in China on July 7, 2023, and granted approval on June 6, 2024—securing exclusive rights to their advanced object rendering technology.

This technique is currently being utilized in Girls’ Frontline 2: Exilium. According to the information available via Google Patents, Sunborn registered a patent for their “silk stocking object rendering method and device.” This technology aims to bridge the gap between hyper-realistic and stylized cartoonish visuals, delivering a more natural look to fabric textures like silk stockings.

Moreover, the development team enhanced the animation physics of these silk stockings, making them behave more naturally during character movement. Through this approach, they successfully achieved "the highlight feeling of real silk stockings," avoiding the all-too-common pitfall of making such materials appear metallic or plastic-like.

Their rendering process involves a detailed workflow—including precise coding instructions, adjustments to light reflection parameters, and refined color transitions—to create a more lifelike appearance. As a result, female characters in Girls’ Frontline 2 are now adorned with visually striking and realistic silk stockings.

Fans of Girls’ Frontline expressed excitement over this news, particularly after a Twitter post by Cleista on December 8. Many praised Yuzhong, Sunborn’s CEO, and the studio’s art team for their meticulous attention to detail. While most users appreciated the innovation, one commenter noted, “I always felt patents like this could potentially harm the game industry.” Nevertheless, the majority of fans agree that the upgraded silk stocking visuals in Girls’ Frontline 2 surpass those seen in the original title.

Sunborn’s patent will remain valid until July 7, 2043, effectively blocking other studios from replicating this specific rendering method for nearly two decades. However, interested parties may seek permission to use the technology, subject to Sunborn’s approval.
