This is a parametric rope bridge asset for Geometry Nodes in Blender 3.x.
NOTE: THIS IS TESTED IN BLENDER 3.0 BUILDS FROM AFTER 24TH JUNE.
Want to make your own? Here's the tutorial
Either append the ETK_ROPE BRIDGE node tree datablock to your scene and then you can put it on any object as you would any Geometry Nodes tree.
If you use the Asset Browser, I've also marked the node tree as an asset so you can just drop the file in your asset library and the browser will be able to pull it up. Find it in the Asset Browser and drag the asset onto an active node tree (it will come in as a group). Then you can change the modifier's target node tree to be the ETK_ROPE BRIDGE and it'll show up on the modifier as above.
Currently Geometry Nodes tree are displayed under the Shading section of the Asset Browser.
Asset Browser is still an experimental feature so expect it to change over time.
