character sticks at T-pose after launching the game

I have a problem with the character. When I “play” the scene on the viewport, the animations of character are normal. But when I “launch” the game, the character’s pose is back to T-pose as if there is no animation on it. Here are the screenshots of my game. I really need help.

Sorry everyone, after few hours of finding where the problem was, I found out that I used the skeleton from another character. So I change the skeleton to the right one, it is back to normal now. But why would “playing in viewport” still work when i used a wrong skeleton?

That’s the same question as “Why you can play a game in viewport with tons of errors but Unreal refuses to package, even when you are okay with the same errors to exsist in the game?”.

It seems Unreal does tons of checks when packaging, making sure every reference is correct etc. I would agree that playing in editor shouldn’t be any different than the actual game, but alas, it happens time to time.

I strongly advice packaging your game time to time and see if everyone is same as they are in Play in Editor. This saved my skin a few times. :slight_smile:
