prompt | Text description of the 3D model to generate (multiline). This parameter is required and cannot be empty. | STRING | Yes | - |
negative_prompt | Text description of what to avoid in the generated model (multiline). Up to 255 characters. Sent to the API only when non-empty. | STRING | No | Up to 255 characters |
model_version | Version of the Tripo model to use for generation (default: v3_1_20260211). | COMBO | No | Multiple options available |
style | No longer supported by Tripo and ignored. Kept for older workflows (default: “None”). | COMBO | No | Multiple options available |
texture | Generate texture maps. Off returns bare geometry and ignores pbr (default: True). | BOOLEAN | No | true / false |
pbr | PBR material maps (base color, metallic, roughness, normal). Requires texture; forced off when texture is off (default: True). | BOOLEAN | No | true / false |
image_seed | Seed used for the image generation stage (default: 42). | INT | No | 0 to 2147483647 |
model_seed | Seed used for the model generation stage (default: 42). | INT | No | 0 to 2147483647 |
texture_seed | Seed used for the texture generation stage (default: 42). | INT | No | 0 to 2147483647 |
texture_quality | Quality of the generated textures. detailed = HD textures, extreme = 8K Ultra textures (default: standard). | COMBO | No | ”standard" "detailed" "extreme” |
face_limit | Maximum face count. -1 lets Tripo pick adaptively (about 1.4M faces on v3.x standard, 2M on detailed). Tripo clamps silently: v2.5 at 500,000, quad meshes at 150,000. (default: -1) | INT | No | -1 to 2000000 |
quad | Quad mesh output. Tripo delivers quad meshes as FBX, so the result arrives on the FBX output and the GLB output stays empty. (default: False) | BOOLEAN | No | true / false |
geometry_quality | Quality of the generated geometry (default: standard). | COMBO | No | ”standard" "detailed” |
smart_low_poly | Low-poly mesh with clean, hand-crafted style topology (500-20,000 faces, quad 500-10,000). Best for simple subjects; complex ones may fail. (default: False) | BOOLEAN | No | true / false |
auto_size | Scale textured models to their real-world size in meters. Tripo stores the size as the model’s scene transform and bakes it in when the model is converted, rigged or retargeted; ignored without texture. (default: True) | BOOLEAN | No | true / false |
