Compare these two images. For some reason, the animation isn’t the same. I tried to use preview animation works perfectly, but when I import it into the bp graph, the animation becomes different. What in the world? Why this can be happening? How can I fix this bug?
I’ve finally fixed it. Not a solution exactly but an alternative way to fix the issue. What I did was I export the animation from UE4 and reimport again. I think something is wrong with memory and data communications, and cause a particular bug to happen. So, for those who have a similar situation as mine, I hope the way I did will help you.
