You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote, based only on the published visual outputs they can inspect: the interactive 3D scene and rendered presentation.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

## Harness Instructions

You are operating Blender through the provided tools. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work. Before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — position and aim the camera, and add or adjust lights so the subject reads clearly. When you are finished, reply with the single word DONE and no tool calls.

## Task

Complete the following Blender task:

<task>

A red sphere of 1 meter diameter resting on a white ground plane — touching it
exactly, neither floating nor sunk. Smooth shading, a plain red material on the
ball, plain white on the floor.

The floor is the sphere, the color, and the contact. The ceiling is presentation:
a soft believable shadow under the ball, a hint of glossiness that catches the
light, and clean framing.

</task>

    The 3D asset has built-in materials.
    The generated model has a normalized size, so re-scaling after generation can be useful.

    Parameters:
    - input_image_paths: The **absolute** paths of input images. Even if only one image is provided, wrap it into a list. Required if Hyper3D Rodin in MAIN_SITE mode.
    - input_image_urls: The URLs of input images. Even if only one image is provided, wrap it into a list. Required if Hyper3D Rodin in FAL_AI mode.
    - bbox_condition: Optional. If given, it has to be a list of ints of length 3. Controls the ratio between [Length, Width, Height] of the model.

    Only one of {input_image_paths, input_image_urls} should be given at a time, depending on the Hyper3D Rodin's current mode.
    Returns a message indicating success or failure.

You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote, based only on the published visual outputs they can inspect: the interactive 3D scene and rendered presentation.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

## Harness Instructions

You are operating Blender through the provided tools. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work. Before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — position and aim the camera, and add or adjust lights so the subject reads clearly. When you are finished, reply with the single word DONE and no tool calls.

## Task

Complete the following Blender task:

<task>

A red sphere of 1 meter diameter resting on a white ground plane — touching it
exactly, neither floating nor sunk. Smooth shading, a plain red material on the
ball, plain white on the floor.

The floor is the sphere, the color, and the contact. The ceiling is presentation:
a soft believable shadow under the ball, a hint of glossiness that catches the
light, and clean framing.

You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote, based only on the published visual outputs they can inspect: the interactive 3D scene and rendered presentation.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

## Harness Instructions

You are operating Blender through the provided tools. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work. Before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — position and aim the camera, and add or adjust lights so the subject reads clearly. When you are finished, reply with the single word DONE and no tool calls.

## Task

Complete the following Blender task:

<task>

A red sphere of 1 meter diameter resting on a white ground plane — touching it
exactly, neither floating nor sunk. Smooth shading, a plain red material on the
ball, plain white on the floor.

The floor is the sphere, the color, and the contact. The ceiling is presentation:
a soft believable shadow under the ball, a hint of glossiness that catches the
light, and clean framing.

You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote, based only on the published visual outputs they can inspect: the interactive 3D scene and rendered presentation.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

## Harness Instructions

You are operating Blender through the provided tools. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work. Before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — position and aim the camera, and add or adjust lights so the subject reads clearly. When you are finished, reply with the single word DONE and no tool calls.

## Task

Complete the following Blender task:

<task>

A red sphere of 1 meter diameter resting on a white ground plane — touching it
exactly, neither floating nor sunk. Smooth shading, a plain red material on the
ball, plain white on the floor.

The floor is the sphere, the color, and the contact. The ceiling is presentation:
a soft believable shadow under the ball, a hint of glossiness that catches the
light, and clean framing.
