Every project I’ve used sequencer in has this problem. In 4.17 and 4.18.
Playing the sequence in the editor works fine but playing it in the game it sometimes skips the first frame of an animation for each shot, so the character just appears in T pose for one frame (I think sometimes more than one frame). Obviously this looks awful!!
I’ve tried all kinds of stuff and searched forums/answerhub but found only a few people with the same issue and no solution.
If anyone knows a fix for this please let me know!
