In an upcoming update, the internal GameObject hierarchy of avatar pedestals will be added to the Udon access blacklist. Scripts trying to access it will break!
I really appreciate that you warn us about that change, and that you give world creators time to adapt, there’s a prefab used to read avatar pictures and I can imagine that many worlds uses that feature.
Short story : I remember when last year my world (Circuit Master) and a few other worlds I knew broke because of a change related to the networking (Instanciated GameObjects cannot send network event anymore), I got a complaint that my world stopped working a few weeks after the update, it took me days of debugging to figure out the issue, and when I wrote a canny I was told that it was an expected behaviour now… All that because there were no regular developer updates back then, and because I missed that one line in the patchnote, and even if I saw that line in the patchnote I wouldn’t have been able to fix the issue in time, that was heavily frustrating for me.
So basically, thank you for warning us about that change.
