Sparc3D

Model ID: model_sparc3d

Capabilities: img23d

LLM Markdown: https://app.scenario.com/api/models/model_sparc3d/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
images	file_array	Yes	-	-	-	-	Upload 1-4 images, starting with the front view. For multi-image input, you can optionally include back, left, and right views (in that order).
requestType	number	No	3	-	-	1, 3	Choose whether to generate just a mesh or a textured 3D asset
resolution	string	No	1024	-	-	512, 1024, 1536, 1536pro	Controls the voxel resolution of the generated 3D asset. Higher values deliver more detail and cleaner topology.

Sparc3D 2.0

Model ID: model_hitem-sparc-3d-2

Capabilities: img23d

LLM Markdown: https://app.scenario.com/api/models/model_hitem-sparc-3d-2/markdown

requestType	number	No	3	-	-	1, 3	Choose whether to generate just a mesh or a textured 3D asset
resolution	string	No	1536	-	-	1536, 1536pro	Controls the voxel resolution of the generated 3D asset. Higher values deliver more detail and cleaner topology.

Sparc3D 2.0 Portrait

Model ID: model_hitem-sparc-3d-portrait-2

Capabilities: img23d

LLM Markdown: https://app.scenario.com/api/models/model_hitem-sparc-3d-portrait-2/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
images	file_array	Yes	-	-	-	-	Upload 1-4 images, starting with the front view. For multi-image input, you can optionally include back, left, and right views (in that order).

Sparc3D 2.1

Model ID: model_hitem-sparc-3d-2-1

Capabilities: img23d

LLM Markdown: https://app.scenario.com/api/models/model_hitem-sparc-3d-2-1/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
images	file_array	Yes	-	-	-	-	Upload 1-4 images, starting with the front view. For multi-image input, you can optionally include back, left, and right views (in that order).
requestType	number	No	3	-	-	1, 3	Choose whether to generate just a mesh or a textured 3D asset
resolution	string	No	1536fast	-	-	1536fast, 1536pro	1536³ Fast balances speed and quality. 1536³ Pro maximizes detail and topology quality.
face	number	No	2000000	100000	2000000	-	Sets the target number of mesh faces. Higher counts yield more complex geometry. Use 500K for lightweight assets, or 2M for high-fidelity results.
pbr	boolean	No	true	-	-	-	Generate a PBR material
