Producer Yoshiyuki Kayabuki, AI engineer Motohiro Kanou, and 3D designer Nori Tanaka presented on the trajectory from Yume Minana\u0026#39;s debut, the Assist Play Streaming system, and AI-based 3D production technology.\u003c/p\u003e\u003cp\u003eKanou explained that early AI-only game streams suffered from poor pacing, leading to the introduction of a human assistant character, Kairo-chan, who handles keyboard inputs and command selections. This reduced stream time and costs, establishing a cooperative streaming style. Tanaka revealed that preparation for the 3D live took only about three months, requiring semi-automated tools for model creation, motion capture, lighting, camera work, and facial expressions. By pre-loading audio and generating productions like a gacha system, then making fine adjustments, the team achieved quality comparable to typical 3D lives with reduced personnel costs.\u003c/p\u003e","blueskyPost":"Yume Minana's 3D live production uses AI to handle streaming bottlenecks, but the human assistant character reveals KLab's bet: automation alone isn't trustworthy for live interaction.","twitterPost":"Yume Minana's AI tools handle production but a human assistant runs the live stream.
