ComfyUI Node: Context Set Transform Pivot Point

Context Set Transform Pivot Point:

The ContextSet_TransformPivotPoint node is designed to modify the pivot point used for transformations in Blender. This node allows you to set the pivot point to various predefined options, such as the center of the bounding box, the 3D cursor, individual origins, the median point, or the active element. By adjusting the pivot point, you can control how transformations like scaling, rotating, and translating are applied to objects in your scene. This can be particularly useful for precise modeling tasks, animation, and other operations where the pivot point's position significantly impacts the outcome.

Context Set Transform Pivot Point Input Parameters:

pivot

The pivot parameter determines the new pivot point for transformations. It accepts one of the following options: BOUNDING_BOX_CENTER, CURSOR, INDIVIDUAL_ORIGINS, MEDIAN_POINT, or ACTIVE_ELEMENT. Each option changes the reference point for transformations, affecting how objects are manipulated in the scene. For example, setting the pivot to CURSOR will use the 3D cursor's position as the transformation center, while BOUNDING_BOX_CENTER will use the center of the object's bounding box. This flexibility allows for more controlled and precise transformations.

Context Set Transform Pivot Point Output Parameters:

This node does not produce any direct output parameters. Instead, it modifies the context within Blender, specifically the pivot point setting for transformations. The impact of this change will be observed in subsequent transformation operations performed in the scene.

Context Set Transform Pivot Point Usage Tips:

• Use the CURSOR option to perform transformations around a specific point in your scene by first positioning the 3D cursor where you want the pivot to be.
• Select INDIVIDUAL_ORIGINS when you need to transform multiple objects around their own origins simultaneously, which is useful for symmetrical modeling or animation.
• Opt for BOUNDING_BOX_CENTER to scale or rotate objects uniformly around their geometric center, ensuring balanced transformations.

Context Set Transform Pivot Point Common Errors and Solutions:

Invalid pivot point selection

• Explanation: The selected pivot point option is not recognized or is misspelled.
• Solution: Ensure that the pivot parameter is set to one of the valid options: BOUNDING_BOX_CENTER, CURSOR, INDIVIDUAL_ORIGINS, MEDIAN_POINT, or ACTIVE_ELEMENT.

No effect on transformations

• Explanation: The pivot point change does not seem to affect transformations.
• Solution: Verify that the node has been executed correctly and that subsequent transformations are being performed after the pivot point has been set. Ensure that the context in Blender is correctly updated by checking the tool settings in the scene.
