Hunyuan 3D 3.1 (Multiview) prioritizes spatial accuracy by reconciling data from up to eight reference images (front, back, left, right, top, bottom, and 45-degree left/right angles). The expanded viewpoint support significantly improves structural accuracy over the 4-view limit in version 3.0, enabling better reconstruction of complex geometries. Providing multiple angles reduces reconstruction ambiguity and eliminates the geometric hallucinations common in single-view models. It outputs 4K HD textures with physically-based rendering (PBR) properties. Effective for complex organic or mechanical subjects requiring exact symmetry. Specs: 1024-1536 resolution; 4K textures; Speed ~90s; Cost: 120 CU.
