Geo Stack Generator

Overview

Stack Generator is a professional Blender add-on designed to create dense, realistic stacks of objects directly on any surface.

Built using Geometry Nodes and instancing, it generates complex piles while keeping your scene fast and responsive.

For best results, assets inside your collection should have similar heights.

• Automatic Center Correction – Internally aligns assets for perfectly grounded piles
• Collection-Based Workflow – Generate stacks instantly from any asset collection
• Procedural Vertical Control – Adjust height, spacing, and variation
• Natural Variation – Add controlled disorder for realism
• Volumetric Masking – Restrict where stacks are generated using a 3D boundary
• Optimized Performance – Smooth viewport with high instance counts
• Clean UI – Intuitive controls directly in the N-Panel
