The developers behind Girls’ Frontline 2: Exilium, MICA Team/Sunborn, have taken a significant step in protecting their unique rendering technology by patenting their method and device for rendering silk stockings. This patent, filed on July 7, 2023, and approved on June 6, 2024, showcases their dedication to achieving a highly realistic visual representation within the game.
Sunborn's patented "silk stocking object rendering method and device" is designed to bridge the gap between realistic and cartoonish visuals, enhancing the in-game experience. By implementing specific coding, adjusting light reflection parameters, and fine-tuning color transitions, they've managed to create silk stockings that reflect the true "highlight feeling of real silk" without appearing metallic or plastic-like.

Protected their Technology to Realistically Render Silk Stockings

The technology is currently in use within Girls’ Frontline 2: Exilium, where it significantly improves the animation physics of the silk stockings worn by female characters. This innovation has not gone unnoticed by fans, with many expressing their excitement and appreciation on social media. A notable post by Cleista on Twitter on December 8 praised Yuzhong, CEO of Sunborn, and the artists for their meticulous attention to detail.
However, there are mixed reactions to the patenting of such techniques. While the majority of fans are thrilled with the improved visuals, some, like one user who commented, "I always felt patent stuff like this only hurt the game industry," see potential downsides to such proprietary practices.
Sunborn's patent on this rendering method will remain in effect until July 7, 2043. During this period, other companies are barred from using this specific technique without obtaining permission from Sunborn, who retains the discretion to approve or deny such requests.
