I made a character rig, and in studio its fine and the animations work. I am using a local script and I dont know what im doing wrong... I thought roblox just had not approved the animations, but its been many days already and it still doesnt work.
if the character rig is a NPC then use a normal script else use a local script. Make sure you set the primary part to the humanoid root part if it is you.
Where is your local script located? If it's in Workspace, you'll need to relocate it to StarterGui, StarterPack, pretty much anything that's not Workspace. If you do that, it might work. You should also post the code so we can see it.
Make sure the rig is the correct R. I had the same problem. If you made an R15 character animation, it will only work for R15 characters. If you made an animation for an R6 character, it'll only work if the player is R6. If I am correct, you might want to go to game settings and choose a rig that all players will be forced to have in game. Then your animations will work.
