3DT Hay Roof Generator – Blender Geometry Node Procedural

🎥 Demo Video

Create detailed, dynamic hay and thatch surfaces instantly with the 3DT Hay Roof Generator — a fast and flexible setup for Blender 4.0+.

Whether you’re building medieval huts, Viking halls, or countryside scenes, this tool allows you to add thick hay, editable in real time with full control over gravity, randomness, thickness, draw mode, and more — no simulation or particles required.

🎯 Key Features

One-Click Hay Generation
Add hay to roofs, bales, or meshes instantly — just apply the geometry node and it’s done.

Gravity-Based Control System
Adjust gravity to bend hay strands naturally — from upright spikes to sagging, rain-drenched curls.

Random Rotation & Length Settings
Add realism with per-strand randomness and dynamic rotation toggles — perfect for stylized chaos or clean bundles.

Viewport Density Scaling
Keep performance high with adjustable density for both preview and render modes.

Draw Mode with Curve Input
Use draw curves to place hay manually in precise locations — great for hay troughs, loose piles, and artistic control.

🔥 Why You'll Love It

Perfect for Medieval, Viking, or Stylized Projects
Ideal for taverns, stables, hay bales, thatch rooftops, and historical structures.

Quickly Shape & Rotate Hay Meshes
Use edit mode and curve drawing to reposition, angle, or adjust hay paths in seconds.

Switch Between Roofs, Bales, or Loose Hay
Works equally well for flat roofs, round cylinders, or manually drawn patches of hay.

Includes Two Stylized Materials
Apply included wood or hay materials — or use your own textures with UV-ready outputs.
