Meshy 6 Lite Text-to-3D turns a text description into a textured 3D model with Meshy’s lightweight model. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Meshy 6 Lite Text-to-3D generates a 3D model directly from a text description. Create an untextured preview or a fully textured model, then optionally configure topology, polygon count, rigging, and animation.


Why Choose This?

  • Text-to-3D generation — Create 3D assets directly from natural-language descriptions.
  • Preview or full generation — Choose an untextured mesh or a textured final model.
  • Texture guidance — Guide the final appearance with a text prompt or reference image.
  • Mesh controls — Choose triangle or quad topology and set a target polygon count.
  • Character preparation — Generate A-pose or T-pose characters for rigging workflows.
  • Optional rigging and animation — Add a character skeleton and preset animation when needed.

Parameters

ParameterRequiredDescription
promptYesDescription of the 3D object, including its shape, materials, and style. Maximum 600 characters.
modeNoGeneration mode: preview returns an untextured mesh, while full also generates textures. Default: full.
negative_promptNoOptional description of features or visual qualities to avoid.
seedNoOptional random seed for generation.
texture_promptNoOptional text description used to guide the generated texture.
texture_imageNoOptional reference image used to guide the texture. If both texture_prompt and texture_image are supplied, texture_prompt takes priority.
enable_pbrNoGenerate PBR maps including metallic, roughness, and normal maps. Default: false.
topologyNoRemeshed topology: triangle or quad. Default: triangle.
target_polycountNoTarget number of polygons when should_remesh=true. Range: 100–300000. Default: 30000.
should_remeshNoRemesh the generated model using the selected topology and target polygon count. Default: true.
symmetry_modeNoDeprecated compatibility parameter. Options: off, auto, or on. Default: auto. It no longer affects the result.
pose_modeNoGenerate the model in a-pose or t-pose. Useful for character rigging workflows.
auto_sizeNoEstimate the object’s real-world height and resize the model accordingly. Default: false.
enable_riggingNoRig the generated humanoid character. The rigged model is returned after the generated model. Default: false.
rigging_height_metersNoApproximate character height in meters used for rigging. Default: 1.7.
enable_animationNoRig and animate the generated character using animation_action_id. The animated model is returned last. Default: false.
animation_action_idNoPreset animation ID applied when enable_animation=true. Default: 92.

How to Use

  1. Describe the object — Enter its shape, materials, style, and important visual details.
  2. Choose generation mode — Use preview for an untextured mesh or full for a textured model.
  3. Configure topology optional — Choose triangle or quad topology and adjust the target polygon count.
  4. Add texture guidance optional — Use a texture prompt or reference image when generating a full model.
  5. Choose pose optional — Use an A-pose or T-pose when preparing a humanoid character for rigging.
  6. Enable rigging or animation optional — Add a skeleton or apply a preset animation.
  7. Submit — Generate and retrieve the available 3D outputs.

Best Use Cases

  • Game assets — Generate textured or optimized 3D models from text.
  • Product concepts — Turn written product ideas into 3D assets.
  • Character generation — Create humanoid characters in A-pose or T-pose.
  • Rigged characters — Generate characters ready for downstream animation.
  • Animated assets — Apply a preset animation directly to generated characters.
  • 3D prototyping — Explore props, objects, characters, and design concepts quickly.

Pro Tips

  • Describe the object’s shape, materials, proportions, and visual style clearly.
  • Use negative_prompt to reduce unwanted features.
  • Use preview for lower-cost geometry testing before generating a full textured model.
  • Use texture_prompt when you want explicit control over materials or surface appearance.
  • Use texture_image when a visual reference is more useful than a written description.
  • Keep should_remesh=true when you need control over topology and polygon count.
  • Use pose_mode for humanoid characters that will be rigged or animated.
  • Use characters with clearly visible limbs and body structure for better rigging results.

Notes

  • prompt is required and supports up to 600 characters.
  • mode defaults to full.
  • preview generates an untextured mesh, so texture-related options are not applied.
  • If both texture_prompt and texture_image are supplied, texture_prompt takes priority.
  • target_polycount supports 100–300000 and applies when should_remesh=true.
  • The final polygon count may differ from the requested target.
  • should_remesh defaults to true for Meshy 6 Lite.
  • symmetry_mode is retained for compatibility but no longer affects the output.
  • auto_size estimates the object’s real-world height and rescales the model accordingly.
  • Rigging and animation are intended for textured humanoid characters with clearly defined limbs and body structure.
  • Rigging supports models up to 380000 triangles; each quad counts as two triangles.
  • enable_animation=true includes the rigging step and applies one preset action using animation_action_id.
