Hunyuan3D vs Unique3D

Hunyuan3D is Tencent’s system for generating 3D assets from text, images, or sketches. The international platform accepts up to four multi-view images, offers model editing and adjustment, and exports OBJ and GLB files. Its capabilities include text-to-3D, image-to-shape, and texture generation; Smart Topology supports triangular and quadrilateral faces. Tencent Cloud documents API tasks for generation, texturing, topology reduction, component generation, UV mapping, motion, auto-rigging, and format conversion. Hunyuan3D-2.1 releases full model weights and training code, and its repository documents a local Gradio app. A Blender add-on is listed for Hunyuan3D-2. The stated VRAM needs are 10 GB for shape generation, 21 GB for texture generation, and 29 GB for both. First-time API activation grants 100 credits, valid for one year. Paid packs include 1,000 credits for 100 CNY, paid once and 10,000 for 980 CNY, paid once; pay-as-you-go is billed at 0.12 yuan per credit, with monthly settlement.

Unique3D generates textured 3D meshes from a single image. Its method derives four orthographic views from the input and progressively increases their resolution, then generates matching normal maps with a normal diffusion model. The project's ISOMER reconstruction algorithm combines color and geometric priors and can produce meshes with millions of faces. The project describes generation from a single-view image in 30 seconds and says a high-fidelity textured mesh from one orthogonal RGB image can be generated in under 30 seconds. Image-to-3D and AI texturing are listed capabilities, and GLB is the listed export format. The repository links to a ComfyUI implementation and provides instructions for an interactive local Gradio demo after model weights are downloaded. An online demo is free to try with a registration invitation code; it is described as slower but more stable than the Gradio demo. The Linux setup targets Ubuntu 22.04.4 LTS and CUDA 12.1, while Windows installation may require Visual Studio Build Tools.
