Scenario GPT-6 Astra 3D

Turn reference images into an editable 3D object — named parts, clean topology, per-part materials. Best for props and hard-surface subjects, not characters.

Model ID: model_scenario-gpt6-astra-3d

Capabilities: img23d, 3d23d, txt23d

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
images	file_array	No	-	-	-	-	Building: 1 to 8 photos of the object, or leave empty to build from the prompt alone. Editing: optional images that guide the change, like a material sample, a logo or a marked-up view of the model.
sceneFile	file	No	-	-	-	-	Optional. Add any 3D model to edit it instead of building a new one. It comes back in the same format.
prompt	string	No	-	-	-	-	Building: describe the object, like “a weathered tugboat with a red hull”, or just name it when you add photos. Editing: describe the change, like “open the lid”.
buildEffort	string	No	high	-	-	standard, high, maximum	Standard for simple objects or small edits like a recolor. High or Maximum for detailed objects, or edits that add or reshape parts. When editing, match it to the change, not the model.
faceBudget	number	No	250000	1000	2000000	-	Max triangles for a new model: 10k–50k for games, 250k for fine detail. Not used when editing.
outputFormat	string	No	auto	-	-	auto, glb, fbx, obj, usdz, stl, ply, blend	Format of the delivered model, which always comes with its Blender file. Auto: a GLB when building, the edited model’s own format when editing. With Quads, an FBX unless the model is already FBX, OBJ, PLY or USDZ.
topology	string	No	auto	-	-	auto, triangles, quads	Faces of the delivered model, checked before it is returned. Auto keeps an edited model’s faces and lets the model choose for a new one.
