Get the Creator Companion
If you login to the vrc website you should be able to find the download in there
You also need unity and it should tell you which year of unity you need, might need the unity hub.
As for converting to a vrm, I suggest looking up a video, most are old but work

Not a recommendation but maybe look on jinxxy or next
Jinxyy if you have an account that allows for nsfw, nexxy for anything in general

done :p

The Kobodal by Nicoreda
nicoreda.gumroad.com/l/Kobodal

I love the avatar and I've ran with it for more than a few years now and it's made me sad that there is so few assets made for em, so it is a price I'm willing to pay

Ngl I will buy it for you

Swimwear for the kobodal?

And good chances are they will appreciate it and end up teasing for fun, but that is also from my experience from both sides

Believe me, despite the name you don't gotta play vrc in vr, I see a ton of people that just play on desktop, and no worries about your voice either I'm sure you sound lovely, there are mute, trans, and peeps that use voice changers from my experience on vrc
