Hunyuan 3D V3.1 Pro
Up to 1.5 million faces. 8-view input. Full PBR materials. The latest from Tencent.
Hunyuan 3D V3.1 Pro is Tencent's latest 3D generation model. It accepts up to 8 reference views (front, back, left, right, top, bottom, plus two diagonals), produces face counts from 40,000 to 1.5 million, generates full PBR materials, and exports to GLB, OBJ, FBX, and USDZ. The two-stage architecture generates geometry first, then applies physically based materials with accurate metallic, roughness, and normal maps.
Example outputs
“An urban EV charging hub with a sweeping curved solar canopy, branded charging column, cars parked beneath, city plaza at golden hour, blueprint overlay in the foreground, infrastructure concept render”
“A baroque gilt picture frame corner detail, ornate acanthus leaf and shell scrollwork, aged gold with subtle verdigris, mounted on a dark gallery wall, warm spotlight from above, interior design photography”
“A Japanese pine bonsai on a low wooden stand in a traditional courtyard, gnarled trunk with detailed bark, dense foliage pads, blue-green rectangular ceramic pot, soft natural light, botanical photography”
“A space exploration helmet with mission patch, gold-tinted reflective visor showing a lab interior, communication antenna and life support hoses, worn white composite shell, sci-fi concept art style”
“A walnut and marble kitchen island with waterfall countertop, brass drawer pulls, open timber shelving with ceramics, glass pendant light above, bright airy interior, design magazine photography”
“A colour-coded anatomical heart cross-section on a display stand, labelled chambers and vessels, educational model with clear casing, clean white background, medical illustration style”

Hunyuan 3D V3.1 Pro is a major step up from V3. Face counts scale from 40,000 for quick concepts to 1.5 million for hero assets. The geometry captures fine surface detail that lower-resolution models miss: panel lines, rivets, fabric folds, organic curves. For architectural visualisation and product design, this level of geometric fidelity reduces the gap between AI-generated and hand-modelled assets.
V3.1 Pro accepts up to 8 reference views: front, back, left, right, top, bottom, and two diagonal angles. The model fuses all perspectives to produce accurate proportions and consistent geometry from every angle. Single-image mode still works when you have one strong reference. Both modes produce the same PBR material quality.
The PBR pipeline generates separate base colour, metallic, roughness, and normal maps through a dedicated material painting stage. This two-stage architecture means the geometry is finalised before materials are applied, producing cleaner material boundaries and more accurate specular response than single-pass models.
Up to 1.5 million faces
Scale geometry from 40K (concept) to 1.5M (hero asset). Higher face counts capture fine surface detail: rivets, seams, fabric texture, organic curves. Choose the density that matches your pipeline.
8-view image input
Upload up to 8 reference views for the most accurate reconstruction possible. The model fuses perspectives for precise proportions. Works with photos, renders, or concept art.
Two-stage PBR pipeline
Geometry is generated first, then PBR materials are painted in a second pass. This produces cleaner material boundaries, accurate metallic separation, and proper specular response.
Five export formats
GLB for web and AR. OBJ for legacy pipelines. FBX for game engines and Maya. USDZ for Apple AR Quick Look. MTL for material data. PBR materials included in all formats.
