All animations play on the server, but as soon as I switch to client, you can see from the gif, some of them do not replicate to client.
Why is this?
Its probably because you are not standing close enough and have streaming enabled or something
Streaming Enabled is disabled & how close do I need to stand?
Not sure, but I know that client has a built in feature to save performance so that it doesn’t play animations on humanoid that are far away (or something along those lines)
Run the game focused as client first. Maybe this is replication bug in Studio because client is not active.
You can see from the gif, that assets weren’t even loaded when you switched to the client.
