How to add custom wind for my own Tree with Nanite Assembles ?

I wanted to test the Nanite Assemblies Tree using Houdini. I’ve used various tutorials to create my own tree with its own instance branches. Everything works, but now I’m running into a problem: I don’t understand how to assign wind. Since I’m more of an environment artist than a technical person, this is quite difficult for me to figure out. I think I heard there’s a way to get a JSON file from Speedtree and insert it into my tree, but I can’t even imagine how to do that. Any ideas on what exactly?
