Scenario produces hundreds of 2D illustrations per week using Stable Diffusion models fine-tuned for specific games, while Layer AI has redesigned the workflow itself for game studios. Promethean AI alone occupies the virtual world builder category, and Charmed pins down character and asset work in a single screen. On the 3D side, Microsoft Trellis, Meshy, Tripo, Rodin Gen-1.5, Sloyd, CSM, and NVIDIA Edify 3D build meshes and topology directly from text and images. In the NPC AI category, Inworld AI has become the standard character SDK integrated into Unity and Unreal, with Convai and NVIDIA ACE (Avatar Cloud Engine) following behind. Ubisoft NEO NPC stunned GDC 2024, and by spring 2026 conversational NPC AI is starting to ship in real games. This article maps the 2026 AI game asset and NPC AI ecosystem end to end — 2D art, 3D models, textures, voice, procedural content generation, and the moves Korean and Japanese studios are making.

Scenario는 게임 전용으로 파인튜닝된 Stable Diffusion 모델로 2D 일러스트를 매주 수백 장 뽑아내고, Layer AI는 워크플로 자체를 게임 스튜디오용으로 재설계했다. Promethean AI는 가상 세계 빌더 카테고리를 단독으로 차지하고, Charmed는 캐릭터·에셋을 한 화면에서 짚어낸다. 3D 쪽에서는 Microsoft Trellis, Meshy, Tripo, Rodin Gen-1.5, Sloyd, CSM, NVIDIA Edify 3D가 텍스트·이미지로부터 직접 메쉬와 토폴로지를 만든다. NPC AI 카테고리에서는 Inworld AI가 Unity와 Unreal에 통합된 캐릭터 SDK의 표준이 되었고, Convai와 NVIDIA ACE(Avatar Cloud Engine)가 그 뒤를 따른다. Ubisoft의 NEO NPC 시연이 2024년 GDC를 흔들었고, 2026년 봄에는 실제 게임에 NPC 대화 AI가 탑재되기 시작했다. 이 글은 2026년의 AI 게임 에셋 + NPC AI 생태계를 처음부터 끝까지 — 2D 아트, 3D 모델, 텍스처, 음성, 절차적 콘텐츠 생성, 그리고 한국·일본 스튜디오의 동향까지 — 한 호흡으로 정리한다.
