The Stocker Helper creates a boundary cube that encompasses selected objects. It calculates the global bounding box, generates a mesh, aligns the origin to the bottom-front-left corner, and applies Geometry Node templates.

Features

Bounding Box Calculation: Calculates the global spatial extent of selected mesh objects.
Origin Alignment: Sets the boundary object's origin to the Back-Left extreme (+Y, -X).
Geometry Nodes Injection: Applies a NODES modifier using templates named grid_pack or circle_pack.
Asset Fetching: Scans registered Asset Libraries for required node groups.
Height Buffer Control: Adds a percentage-based buffer to the Z-height via a slider.
UI: Access via the Stocker tab in the 3D Viewport N-Panel.

Requirements

Blender Version: 4.5
Node Group Templates: The .blend file or the Stocker Asset Library must contain Geometry Node groups named grid_pack and circle_pack.

Installation

Download stocker.zip.
Drag the .zip file into Blender.

Usage

Select Objects: Select the objects for the packing area.
Open Sidebar: Press N in the 3D Viewport.
Locate Tab: Click the Stocker tab.
Adjust Height Buffer: Set the height buffer percentage.
Run Setup: Click Grid Boundary or Circle Boundary.
Result: An object named Stocker_Boundary is created with the configured Geometry Nodes modifier and origin.

Recent Improvements

Asset Library Scan: Implemented priority for "stocker" libraries and automatic appending of missing node groups.
Code Robustness: Updated imports and classmethod poll attributes for Blender Extension compliance.
