NameDescription

Parameters:

  • max_size: Maximum size in pixels for the largest dimension (default: 800)

Returns the screenshot as an Image.

execute_blender_codeB

Execute arbitrary Python code in Blender. Make sure to do it step-by-step by breaking it into smaller chunks.

Parameters:

  • code: The Python code to execute

get_polyhaven_categoriesA

Get a list of categories for a specific asset type on Polyhaven.

Parameters:

  • asset_type: The type of asset to get categories for (hdris, textures, models, all)

search_polyhaven_assetsA

Search for assets on Polyhaven with optional filtering.

Parameters:

  • asset_type: Type of assets to search for (hdris, textures, models, all)

  • categories: Optional comma-separated list of categories to filter by

Returns a list of matching assets with basic information.

download_polyhaven_assetA

Download and import a Polyhaven asset into Blender.

Parameters:

  • asset_id: The ID of the asset to download

  • asset_type: The type of asset (hdris, textures, models)

  • resolution: The resolution to download (e.g., 1k, 2k, 4k)

  • file_format: Optional file format (e.g., hdr, exr for HDRIs; jpg, png for textures; gltf, fbx for models)

Returns a message indicating success or failure.

set_textureA

Apply a previously downloaded Polyhaven texture to an object.

Parameters:

  • object_name: Name of the object to apply the texture to

  • texture_id: ID of the Polyhaven texture to apply (must be downloaded first)

Returns a message indicating success or failure.

get_polyhaven_statusA

Check if PolyHaven integration is enabled in Blender. Returns a message indicating whether PolyHaven features are available.

get_hyper3d_statusA

Check if Hyper3D Rodin integration is enabled in Blender. Returns a message indicating whether Hyper3D Rodin features are available.

Don't emphasize the key type in the returned message, but sliently remember it.

get_sketchfab_statusA

Check if Sketchfab integration is enabled in Blender. Returns a message indicating whether Sketchfab features are available.

search_sketchfab_modelsA

Search for models on Sketchfab with optional filtering.

Parameters:

  • query: Text to search for

  • categories: Optional comma-separated list of categories

  • count: Maximum number of results to return (default 20)

  • downloadable: Whether to include only downloadable models (default True)

Returns a formatted list of matching models.

download_sketchfab_modelA

Download and import a Sketchfab model by its UID.

Parameters:

  • uid: The unique identifier of the Sketchfab model

Returns a message indicating success or failure. The model must be downloadable and you must have proper access rights.

generate_hyper3d_model_via_textA

Generate 3D asset using Hyper3D by giving description of the desired asset, and import the asset into Blender. The 3D asset has built-in materials. The generated model has a normalized size, so re-scaling after generation can be useful.

Parameters:

  • text_prompt: A short description of the desired model in English.

  • bbox_condition: Optional. If given, it has to be a list of floats of length 3. Controls the ratio between [Length, Width, Height] of the model.

Returns a message indicating success or failure.

generate_hyper3d_model_via_imagesA

Generate 3D asset using Hyper3D by giving images of the wanted asset, and import the generated asset into Blender. 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.

poll_rodin_job_statusA

Check if the Hyper3D Rodin generation task is completed.

For Hyper3D Rodin mode MAIN_SITE: Parameters: - subscription_key: The subscription_key given in the generate model step.

Returns a list of status. The task is done if all status are "Done".
If "Failed" showed up, the generating process failed.
This is a polling API, so only proceed if the status are finally determined ("Done" or "Canceled").

For Hyper3D Rodin mode FAL_AI: Parameters: - request_id: The request_id given in the generate model step.

Returns the generation task status. The task is done if status is "COMPLETED".
The task is in progress if status is "IN_PROGRESS".
If status other than "COMPLETED", "IN_PROGRESS", "IN_QUEUE" showed up, the generating process might be failed.
This is a polling API, so only proceed if the status are finally determined ("COMPLETED" or some failed state).
import_generated_assetA

Import the asset generated by Hyper3D Rodin after the generation task is completed.

Parameters:

  • name: The name of the object in scene

  • task_uuid: For Hyper3D Rodin mode MAIN_SITE: The task_uuid given in the generate model step.

  • request_id: For Hyper3D Rodin mode FAL_AI: The request_id given in the generate model step.

Only give one of {task_uuid, request_id} based on the Hyper3D Rodin Mode! Return if the asset has been imported successfully.

TDQS

A3.5/5.0

Scored across 17 tools

Disambiguation3/5

Most tools have distinct purposes, but there is some overlap and ambiguity. For example, download_polyhaven_asset and set_texture both handle Polyhaven assets, but one downloads and imports while the other applies textures, which could confuse agents about workflow steps. Similarly, generate_hyper3d_model_via_images and generate_hyper3d_model_via_text are clearly different in input method, but their similar names and shared import functionality might lead to misselection if the agent isn't careful. Overall, descriptions help clarify, but the boundaries aren't perfectly clear.

Naming Consistency4/5

Tool names follow a consistent verb_noun pattern with snake_case throughout, such as download_polyhaven_asset, get_scene_info, and search_sketchfab_models. There are minor deviations like execute_blender_code (which uses 'execute' instead of 'run' or similar, but it's still a verb) and poll_rodin_job_status (which includes 'job' in the noun part, slightly breaking the pure verb_noun flow). Overall, the naming is highly predictable and readable.

Tool Count4/5

With 17 tools, the count is slightly high but reasonable for a Blender integration server that covers multiple external services (Polyhaven, Sketchfab, Hyper3D) and core Blender operations. It feels comprehensive rather than bloated, as each tool serves a specific function like downloading assets, generating models, or getting scene info. However, it borders on being heavy, which might overwhelm agents but is justified by the broad scope.

Completeness4/5

The tool set provides good coverage for asset sourcing (Polyhaven, Sketchfab), 3D model generation (Hyper3D), and scene management in Blender. It includes key operations like download, search, status checks, and import. Minor gaps exist, such as no tools for editing or deleting objects in Blender beyond basic info retrieval, and limited texture management (only set_texture without broader material handling). Agents can work around these, but the surface isn't fully comprehensive for advanced Blender workflows.
