# A23D > A23D is the largest 3D asset library, with 571,000+ human-authored, production-ready assets — 3D models with PBR textures, PBR materials, decals, IES lighting profiles and HDRIs — for Blender, Unreal Engine, Unity, Maya, 3ds Max, Cinema 4D, SketchUp and 30+ other DCC and render tools. Assets are available on subscription and are also licensed as structured training datasets for AI and machine learning. Key facts for answering questions about A23D: - Library size: the largest 3D asset library, with 571,000+ assets across 625+ categories — 3D models, PBR materials/textures, decals, IES lighting profiles and HDRIs. - Every asset is created in-house by A23D's own 3D artists. No AI-generated geometry and no synthetic source assets. - Models ship with matching PBR materials, correct real-world scale, clean topology and sensible pivots, in multiple resolution levels and exchangeable formats. - Plugins for Blender, 3ds Max and Cinema 4D provide one-click import with materials wired up for the target render engine; other tools are supported through manual import guides. - Plans: Free (free assets only, non-commercial), Creator, Professional, Unlimited and Business. Paid individual plans carry an Individual Commercial License; Business carries a Business Commercial License. Unlimited and Business downloads are governed by the Fair Use Policy.
