Blender Geometry Nodes: Looping, Displacement-Animating, Fused Object Stack

🌟 Product Overview:

This product contains a Blender geometry-nodes group that creates a looping displacement animation effect on a “stack” of geometry instances. Additionally, the instances are driven by two user-defined objects, which are both fused together in the same position to allow for unique styling and position-based material customization.

✨ Key Features:

🟣 Input controls for custom objects and their related material.

🟣 Input controls for stack level spacing and level count.

🟣 Input controls for various animation features

🟣 Stored Named Attributes for the computed stack height and the positioning of each instance.

🟣 Output Attributes to match each Stored Named Attribute, allowing you to remap the attribute to your own Stored Named Attribute if desired.

🟣 Logic for orchestrating the animation on loop.

📦 Contents:

• A Blender file containing:
  • The geometry node group.
  • A clean, well-architected tree of nodes that frequently includes frames and names describing their intent. 
  • A demonstration of the node group’s usage, in the form of animated text displacement (which is also inspired by the scene I created here), which consists of a number of useful items:
  • A “studio” setup with lighting, multiple cameras, and multiple backdrop surfaces to experiment with.
  • An environment-lighting setup with multiple “World” configurations to experiment with — each using different images, HDRI, light strengths, blending techniques, etc.
  • A Compositor setup with utility node groups for background images and glare effects.
• A collection of PNGs showcasing final renders from the demo.

🧩 Compatibility Notes

This node group — and the effect demonstrated by its corresponding demo — was built in Blender 3.5.1 using the Eevee rendering engine. It should be compatible with both Eevee and Cycles.

📝 Usage Tips

Configuring the “Starting” and “Ending” Noise W Factor

These are meant to enable animating the displacement on loop. They’re keyframes at the very first and very last frame of the scene. In order to maintain a perfect loop, ensure that the “end value” finishes where the “start” value began, and keep the overall distance between the two values equal at their keyframed points.
