據外媒消息，《CGWORLD》2026年11月刊稱，《惡靈古堡9》開發團隊為女主角葛蕾斯做了一頂真實假髮，用來參考角色髮型變化。團隊先與髮型、化妝專家合作完成假髮，再用CG創建髮型，並以它作為Strand Hair技術的參考，從而更細緻地還原葛蕾斯的頭髮表情，連頭皮毛孔等細節也包括在內。
💅Resident Evil Requiem developers used a real wig to create Grace's Hairstyle. According to CGWORLD 2026 November issue, before creating Grace's hairstyle in CG, the developers worked with a hair and makeup specialist to create a real wig. 👩🦳 The wig was then used as a reference for Capcom's Strand Hair technology, allowing the team to recreate her hair in detail, down to the pores of the scalp. For the scene early in the game where Grace is hanging upside down, the developers also hung the real wig upside down to study how the hair moved, how elastic it was, and how light passed through it when backlit. 🙂 They used the results to improve the hair simulation in Strand Hair and make the movement look more convincing. The team also created a special shader specifically for this cutscene to reproduce the redness of Grace's face, sweat, and other effects, rather than using the standard in-game shader. https://twitter.com/RENews_X/status/2111473078903738638
雜誌提到，在遊戲早期場景中，比如葛蕾斯倒掛時，團隊也會把真實假髮倒掛起來，觀察頭髮如何移動、彈性如何，以及背光時怎樣透光。他們據此改進Strand Hair的頭髮模擬，讓頭髮運動更逼真。
此外，團隊還為相關過場動畫單獨製作了著色器，用來表現葛蕾斯臉上的紅暈、汗水等效果，而不是直接使用遊戲標準著色器。報道認為，這些製作細節說明團隊希望從真實物理表現出發，提升角色頭髮和過場動畫的視覺效果。
