• Avatar Partially Loading: If you did not use a Texture Atlas size selected in yout Avatar Config, you will receive avatar in multiple meshes and you might observe only eyes of the avatar being loaded and that you are getting an IndexOutOfRangeException: Index was outside the bounds of the array. error message. Multiple mesh avatars are not yet supported in the package so please use a config with atlas size selected.
• Shared Access Violation Error: When you test your build locally, all the game instances will try to write avatar file at the same time due to first time download and cause a file read error. Even though remote players won't experience this issue it is troubling while testing your app. You might test with same avatars and after they are cached this issue should not occur.
