No, I will not.

Only if there is NO file sharing, involved, for example that your friend guides you in a voice call or chat, OR you can ask any of my trusted people in my server such as my admin, my friends or from another person that owns the avatar.

There are usually patch notes at the bottom of the product page if any problems are fixed. Send a picture in my Discord server if you can't find anything stating that this has been fixed.

No, some yellow warnings such as "Bone x not being a child of bone z", or "The avatar uses a mixture of Write defaults" are intended. Do not change anything as it could break the avatar. You can still upload them.

Absolutely not, both of you need your own license to the product.

Absolutely not. The avatar may only be uploaded privately.

No. There are plenty of tutorials on how to upload avatars and help channels to ask in. I can help in my own server if I got time.

No. If you edit the avatar/asset you are responsible to fix it yourself.

Make sure to look through what things you need to have in your Unity project before importing the avatar package. If you are having problems even from a fresh download of the Unity package/FBX you can write in my Discord server and tell me what the problem is. It can be a possibility that I have forgotten to update something.

Thank you for wanting to reach out to me about it, this is very important to me that the creators are properly credited. I triple check but still miss things sometimess. You are very welcome to join my server and contact me!
