Mirroring animations

[aftonmason84]

Hi all, I'm asking to see if there is any easy way to mirror animations of an object (i.e., object A moves to the left 20m, but when mirrored it moves to the right by 20m instead) easily without making the scale negative. The reason the scale must remain positive is that the game engine I am exporting this to does not support negative scale and will invert the scale back to positive upon export, completely messing up the position of the object in game. It also means I can't use any special modifiers that are not exportable. I have a lot of objects with complex animations that I would essentially have to redo if there is no way to copy them and mirror them without using the mirror tool. https://omegle.onl/

you can set by flip animate curve , if there are lots nodes , you may need set by script

as your example , your A at [100,100,100] at time 0f , and next key at 100f move to [80,100,100] , then you set 100f to [120,100,100] , your animation changed to move right 20 from move left 20

Maybe you could first use a negative scale on a parent helper, and then later bake the animation of the children?

Here is a little utility for that in case you want to try.
