So the tutorial I followed is on the discord for Liindy, who is a pretty prominent vrchat asset maker. Here is their gumroad page: https://liindy.gumroad.com/

Here is the direct link to their discord: https://discord.gg/5UvWvqvfBH

And here is a direct link to the vid: https://cdn.discordapp.com/attachments/1146516543178543144/1146516898620657785/radialsShowcase.mp4?ex=65551291&is=65429d91&hm=4b659844e4af1ad3b40c9659a3a38e1426fddb89d94268c72b84db0c44175d7b&

Edit: just realized that link to the vid is for a direct download. If you don't want to download it, you can find it on their discord in the "helpful vrc unity stuff" section. Its one of the first posts in that section.
