(For the Meta Avatar Team) The Network Avatar Building Blocks No Longer work...since 24.1.1

[ImmersiveMatthew]

Dear Meta Avatar team.

I(we) tried the Meta Avatar Multiple Player Building Blocks and it does not work with ANY Meta Avatar package above 24.1.1 for both the Unity Multiplayer and the Photon Fusion versions. If you follow this tutorial from Valem, note that at 14:14 when he presses play, you see the Local and Remove Avatar spawn.  I too can achieve this with the Meta Avatars 24.1.1 but anything newer the local and remote avatars do not appear.  

To test yourself create a fresh project with Unity 2022.3.x and the All in one SDK 65.0.0 and Meta Avatars 24.1.1 just like the linked tutorial.  Drag the Camera Rig, Auto Matching and the Network Avatar into the scene once for Fusion install and another for the Unity Multiplayer version and both times press play. Note the local and remote avatars appear as expected and as seen on the tutorial. Then update the Meta Avatars to anything newer than 24.1.1, press play and note the local and remote avatar does not appear.  You can update the All in one SDK to 69 and the same.  You can update Unity to Unity 6000.0.27f1 and it is the same.

I have opened a ticket #59230. 

Many developers are burning weeks to get the new Avatars running but there seems to be some fundamental SDK issues.  You told us at Connect that we have to migrate to them by the end of March 2025 so we are hoping we can get one of the dedicated migrations teams to help us that Jill talked about between 14:00 and 16:00 at their Connect talk. https://developers.facebook.com/m/meta-connect-developer-sessions/meta-avatars-sdk/

I went back and tested Netcode and I too am having some odd issues with the remote avatars not spawning, but I did confirm it was working before I posted yesterday so I spent the morning playing around and what I discovered is that if the remote player is on a Quest 3, they do not appear, if they are on a Quest 2 they do appear.  Weird

latest post on this thread by XeniaDev shows a solution for null avatar references when trying to instantiate at runtime.

Can confirm that this solves the avatars not showing up, when using two instances of the desktop simulator it shows the avatars for both the host and the client without any errors, although the update rate for the avatars seems to be quite lagged behind the movement of the name tag. It also doesn't show hand changes.
