Hey I really need help..

ok well, the title is a bit confusing... anyway, I really need help with something in VR. In VR, there's a game called Bonelab, and it's a sandbox/story mode game. Now there are these mods and custom avatars that u can download and use in our game. now ive been playing Bonlab for a few months, and I wanna learn how to make my own avatar. But the Problem is that I don't really know how to make my own avatar, okay, and ik there's a bunch of tutorials, but my Unity doesn't like me... For some reason, there are a bunch of errors, and I tried so many times, but it didn't work. I need someone experienced, and who actually does those custom bonelab avatars. If someone sees this and knows how to make custom avatars, Please dm me on Discord. Here is my Discord user: za4tar Oh, and I need someone that's for free

Thanks and see you guys have a nice day. : )
