Optimize 3D model topology. Supports GLB and OBJ formats. Max 200MB.
3D prompts work best when they describe silhouette, materials, and output intent. The stronger the build brief, the more usable the resulting asset becomes.
Best results start with a clear subject, materials, and output goal.
Hunyuan 3D V3.1 Optimize Model
Optimize 3D model topology. Supports GLB and OBJ formats. Max 200MB.
Lead with silhouette before detail.
Materials help the model resolve form more clearly.
Say what the asset is for: product, game, animation, visualization.
Refinement should serve the pipeline, not just aesthetics.
A strong 3D prompt defines silhouette, materials, and final use so the result feels buildable instead of vague.
Describe the subject, silhouette, scale, and material language so the asset has a clear physical identity.
Use images or multi-view inputs when the object shape needs to survive more accurately.
Improve the asset once the core shape works so it fits better into game, product, or visualization workflows.
Hunyuan 3D V3.1 Optimize Model is strongest when the prompt reads like a build spec instead of a loose concept caption.
Use it for product forms, environment props, stylized assets, or 3D pipelines that need a strong starting mesh.
When refining, optimize toward the final destination instead of trying to solve everything in the first prompt.
Say what the object is and how it should read at a glance before chasing detail.
Describe the surface language and what the asset is meant for so the model has a stronger target.
Once the form is correct, improve readiness for texturing, animation, or export instead of starting over.
Use image generation first when you need a clearer concept frame before turning it into an asset.
Once the form works, stylization tools can push the asset into a more distinct final language.
