Girls’ Frontline 2 Devs Patented Rendering Method and Device

Protected their Technology to Realistically Render Silk Stockings

MICA Team/Sunborn patents their device and method of rendering silk stockings in games. The patent application was filed in China on July 7, 2023, and approved on June 6, 2024, securing exclusive rights to their object rendering technology.

Sunborn patented their rendering technique and tool, currently used for Girls’ Frontline 2: Exilium. According to Google Patents, Sunborn patented their "silk stocking object rendering method and device," which bridges the gap between realistically rendered stockings and more cartoonish ones. Through this method, they also improved the animation physics to their silk stockings.

Sunborn’s rendering method achieves "the highlight feeling of the real silk stocking," avoiding the common issue of making them appear metallic or plastic-like. They listed multiple steps to achieve this, including using specific codes, adjusting light reflection parameters, and fine-tuning color transitions. In doing so, they created better-looking silk stockings for the Girls’ Frontline 2’s female characters.

Many Girls’ Frontline fans are happy with this revelation on a Twitter post made by Cleista on December 8. They praised Yuzhong, the CEO of Sunborn, and the company’s artists for their attention to detail and commitment to make realistically-looking stockings. However, another user mentioned, "I always felt patent stuff like this only hurt the game industry." Despite this, most fans are thrilled that the silk stockings in Girls’ Frontline 2 look better than in the previous game.

With that being said, Sunborn's patent will expire on July 7, 2043, preventing other companies from using this specific rendering method to create realistic silk stockings for nearly twenty years. However, they can request permission to use this rendering technique, with approval at Sunborn's discretion.
