Hunyuan3D vs Sloyd

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.

Sloyd generates 3D models from text prompts or images and provides tools to refine them without extensive manual 3D work. Its handcrafted parametric templates use sliders for changing shapes, proportions, and details. Other tools cover AI rigging and animation, image creation and editing, retexturing, 4K texture editing, and skybox generation. Users can set target polygon counts and choose quad topology for manual editing or animation. The authenticated REST API handles asynchronous generation and editing jobs, with controls for polycount, topology, and texture resolution. Native plugins are available for Roblox, Unity, Unreal, Godot, Maya, and Blender. Plugin exports include FBX, GLB, and OBJ; API downloads also include USD, USDZ, BLEND, PLY, STL, and 3MF. The free Guest plan allows one AI generation per day and community-model downloads only. Sloyd Plus costs $15 a month, while Sloyd Pro costs $50 a month; both include commercial use, and marketplace reselling is limited to Pro.
