Experiment with Blender Geometry Nodes

[ElmarJ]

Blender 3.0 introduced Geomentry Nodes, which allows (Houdini like) procedural generation of 3D-objects, e.g. depending on dimensions. This could be ideal for the generation of many elements, e.g. bridges, fences and even entire facades.

Unity now has (experimental, beta) support for importing Geometry Nodes (https://docs.unity3d.com/Packages/com.unity.meshsync@0.13/manual/GeometryNodes.html), which opens up this powerful feature for usage in Unity.
