Hay, Straw & Thatch Toolkit — Blender Geometry Nodes & PBR Study

A modular Blender Geometry Nodes and PBR toolkit for building hay, straw and thatch across rural, medieval and fantasy environments.

The project combines rectangular and rolled bales, a reshapeable loose pile, fitted wagon loads, ground scatter, decals, flyaway cards, trims and three thatched-roof treatments. The support meshes stay simple while layered alpha-card clusters provide the breakup and silhouette detail.

The included Scatter on Surface setup exposes density, distribution, masks, alignment, scale, rotation and randomisation. Procedural assets can be realised and converted when a destination pipeline requires actual geometry.

The pack contains one Blender project with 23 core prototype objects plus 11 PBR texture sets and 62 standalone PNG maps. It was built in the Blender 5.1 era and verified in Blender 5.2 LTS with Cycles.
