Generic Animation: Is there a way to mirror generic clips?

    Hey, I chose to go with generic animation instead of humanoid for aesthetic reasons for my 3D side scroller game. I've come to the point where I'm ready to mirror my anims now but I can't seem to find a way to do it with Generic.

    The mirror check box is there in the animator but has no effect. Does anyone know if it is possible to mirror a generic animation? If not are there any other methods of gaining the same results without having to animate everything again?

    Many thanks! Rob

    As far as I know you don't have that option, it's available only for humanoid rigs.

    In this post (mirror clips) you can find an editor script which allows you to get it. You have to decide if it's worth the CPU overhead of this script compared with the memory overhead of having 2 animations.

    Another approach nobody seems to like is to swap the local scale of the mesh to -1. It's worth a try though.

    I hope this helps.

    We cannot mirror generic animation because we don't know if the hierarchy can be mirror. For a humanoid rig there is a pre define set of transform that must be there to apply an humanoid rig so it pretty easy to mirror such a rig, For generic it could be a chair, a door, etc...

    This is not recommended, as negative scaling a skinnedMesh can lead to performance issue.

    Hey man, thanks for replying.

    Ah ok, thanks for the info. I would use a humanoid rig, but I cant animate the translate on bones and create the bouncy/stretchy aesthetic im looking for. So I'll just put in the extra effort and get animating.

    We did add support for Translation animation on Humanoid rig in 5.2 to improve Biped support. We are supporting right now a few bone only: Upper Leg, shoulder, spines and neck.
    But eventually we would like to add support for more bone

    Sorry, just to clarify. When you said 5.2, you did mean 5.2 right? Not the 5.1 that just came out to the public?
    So it'd be out in a few months or so?

    Many Thanks!

    when is 5.2 available? for using generic couldn't you just allow mirroring and it be up to the developer to ensure the skeleton can mirror? if breaks or looks dump then it's my fault. this would be more flexible and would allow non-biped to mirror. Or allow us to create a skeleton mapping in which you could use to mirror.

    2020 and we still don't have this. I really need it. I don't want to try and make two different animations that look exactly the same.
    I can't use the Humanoid avatar option because it buggs out my animations and just isn't worth the effort

    ^^ same here. I have to use Legacy everything and flip the scale, damn the performance cost.

    I really need this too, having to copy and edit every animation by hand is incredibly time consuming, not to mention finding the correctly mirrored rotations :/

    Thanks for the reply, when you said negative scaling, does that include negative scaling in the parent object of skinnedMesh as well

    +1 for the ability to mirror generic animations. This would be a major time saver!

    I understand that you cannot predict what can and cant be mirrored but wouldn't a simple naming convention like Beast-Leg_L, Beast-Leg_R + an error log if only 1 is found let you know straight away if an element is mirrorable?

    Wouldn't it just work to mirror an animation by putting the scale of x to -1?
