Input

Field	Kind	Default	Description
`image_url` required	URL or file	—	Image URL or base64 data URI for 3D model creation. Supports .jpg, .jpeg, and .png formats. Also supports AVIF and HEIF formats which will be automatically converted.
`model_type`	one of standard, lowpoly, smart-topology, smart-topology-t2	standard	Type of 3D mesh generation. 'standard' produces a regular high-detail mesh; 'lowpoly' produces a low-poly mesh optimized for cleaner polygons; 'smart-topology' (Smart Topology T2.5) and 'smart-topology-t2' (Smart Topology T2) produce clean, triangle-only meshes with natively separated parts — T2.5 has sharper detail, T2 is faster. When set to 'lowpoly', the remesh controls (topology, target_polycount, should_remesh) are ignored by Meshy.
`topology`	one of quad, triangle	triangle	Specify the topology of the generated model. Quad for smooth surfaces, Triangle for detailed geometry.
`target_polycount`	number (whole) 100 to 300000	30000	Target number of polygons in the generated model. When model_type is a smart topology option and this is left unset, that model's default is used instead (15,000 for T2.5, 4,000 for T2); the maximum is 30,000 for T2.5 and 15,000 for T2.
`symmetry_mode`	one of off, auto, on	auto	Controls symmetry behavior during model generation. Off disables symmetry, Auto determines it automatically, On enforces symmetry.
`should_remesh`	true or false	true	Whether to enable the remesh phase
`should_texture`	true or false	true	Whether to generate textures
`enable_pbr`	true or false	false	Generate PBR Maps (metallic, roughness, normal) in addition to base color
`is_a_t_pose`	true or false	false	Deprecated: use pose_mode instead. When true, generates a T-pose model.
`pose_mode`	one of a-pose, t-pose,		Pose mode for the generated model. 'a-pose' generates an A-pose, 't-pose' generates a T-pose, empty string for no specific pose.
`texture_prompt`	text	—	Text prompt to guide the texturing process
`texture_image_url`	URL or file	—	2D image to guide the texturing process
`enable_rigging`	true or false	false	Automatically rig the generated model as a humanoid character. Includes basic walking and running animations. Best results with humanoid characters that have clearly defined limbs.
`rigging_height_meters`	number	1.7	Approximate height of the character in meters. Only used when enable_rigging is true.
`enable_animation`	true or false	false	Apply an animation preset to the rigged model. Requires enable_rigging to be true.
`animation_action_id`	number (whole)	92	Animation preset ID from Meshy's library. Only used when enable_animation is true; in that case it must be in [0, 696] (``0`` is the "Idle" preset) and is otherwise rejected with a 422. See https://docs.meshy.ai/en/api/animation-library for available action IDs.
