Hunyuan3D 2.5 follows two-stages pipeline of its previous version Hunyuan3D 2.0, while demonstrating substantial advancements in both shape and texture generation. In terms of shape generation, we introduce a new shape foundation model -- LATTICE, which is trained with scaled high-quality datasets, model-size, and compute. Our largest model reaches 10B parameters and generates sharp and detailed 3D shape with precise image-3D following while keeping mesh surface clean and smooth, significantly closing the gap between generated and handcrafted 3D shapes. In terms of texture generation, it is upgraded with phyiscal-based rendering (PBR) via a novel multi-view architecture extended from Hunyuan3D 2.0 Paint model. Our extensive evaluation shows that Hunyuan3D 2.5 significantly outperforms previous methods in both shape and end-to-end texture generation.","external_url":"https://arxiv.org/abs/2506.16504","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-10T17:37:26.230280+00:00","pith_arxiv_id":"2506.16504","created_at":"2026-05-09T22:54:16.478498+00:00","updated_at":"2026-07-10T17:37:26.230280+00:00","title_quality_ok":true,"display_title":"Hunyuan3D 2.5: Towards High-Fidelity 3D Assets Generation with Ultimate Details","render_title":"Hunyuan3D 2.5: Towards High-Fidelity 3D Assets Generation with Ultimate Details"},"hub":{"state":{"work_id":"94fe94cc-10de-4093-be65-3170f7e638cb","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":40,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2026-01-16T11:11:33+00:00","last_pith_cited_at":"2026-07-08T18:02:57+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-21T19:39:27.175261+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":9},{"context_role":"baseline","n":1}],"polarity_counts":[{"context_polarity":"background","n":9},{"context_polarity":"baseline","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
