Tencent Hunyuan 3D v2.5 goes 10B with ultra-HD meshes

AI-generated 3D models usually look like melted plastic, requiring hours of manual clean-up before they are usable in any real game engine.

Tencent Hunyuan just launched its 3D AI Creation Engine v2.5, aiming to fix that messy geometry with brute force and smarter pipelines. The underlying geometric model jumped from 1B to 10B parameters, boosting mesh polygon count by 10x and reaching 1024-resolution geometric details.

Ready for the animation pipeline

Beyond sharper edges and smoother surfaces, the engine now supports high-grade textures and bump mapping, alongside what Tencent claims is the industry's first multi-view PBR generation for realistic lighting.

Rigging also got an overhaul. The update brings automatic bone binding and skin weight assignment to streamline animation setups. It also introduces pipeline templates for mesh reduction in text-to-3D and image-to-3D workflows, plus multi-view asset generation.

Tencent doubled the daily free web tier to 20 generations and pushed the API live on Tencent Cloud.

Why it matters

Game developers and animators care about usability, not raw novelty. Generated meshes with terrible topology and missing rigs are practically useless in production. By combining a 10B parameter model with PBR textures and automated auto-rigging, Hunyuan is directly targeting the boring bottlenecks that keep 3D AI out of actual studio pipelines.

We think doubling the free quota and opening the API shows Tencent wants indie creators hooked quickly. The real test now is whether those automatic skin weights actually hold up when characters start bending in complex animations.
