Batch Asset Placer

This addon adds a button to the Asset Browser header that allows you to add all selected assets to the scene at the 3D cursor location.

Features:

• Adds assets from external .blend files (User Library, custom libraries).
• Adds assets from the current file (creates copies).
• The first asset is placed exactly at the 3D cursor position; subsequent assets are placed to the right along the X axis. Rows are automatically created when adding more than 10 assets, with additional rows extending along the Y axis.
• Adjustable spacing between assets (default: 0.5).
• Automatically removes duplicate materials, replacing them with originals.

Usage:

• Open the Asset Browser.
• Select one or more assets (hold Shift or Ctrl for multiple selection).
• Click the "Add Selected Assets" button in the Asset Browser header.
• Adjust the spacing value next to the button if needed.

Assets will be added to the scene at the 3D cursor location.

Button Location: The button appears in the Asset Browser header, to the right of existing buttons.

Reason for the .001 suffix:

• When an asset is added to the scene programmatically, Blender marks it as "Mark Asset". To remove this mark, you need to create a duplicate and delete the original. However, the duplicate then receives a numeric suffix (.001) in its name.
