My blender animation is upside down ;-<

I use blender to make model and animation, but for some reason my animations are upside down. I used the same set export before and there was no problem. I am pretty confused… What are the possible causes? I export it to fbx.

Or, it there a way to edit animation in the engine?

When you import an animation, you can modify the translation and rotation of the animation. Try changing the x,y, or z value to 180. If it doesnt work, delete the animation from Unreal, reimport it and try again
