I'm looking for an IK mirroring function.

I watched the video.

I was asking IK, not FK.

Currently, IK can be copied to the other side by selecting only one location.

What I want is to select both and exchange values ​​for each other.

It works the same way for IK and FK. To copy an IK handle to the other side, select the handle and click on "Copy to other side". In order to exchange the two sides, select both handles and click on "Copy to other side". If you have an IK pole handle, do the same with the pole handle.

When you have mirror editing enabled, the handle on the other side is mirrored automatically (just like in FK).

If mirroring/copy to other side does not work for your IK handle, go into config mode and check if the mirror mapping is correct (for the IK handles).

Please let me know in case you have any follow-up questions.

PS: I deleted the duplicated forum thread. Please keep the conversion regarding this topic in this thread.

Best regards,

If you select the left arm ik in the scene window and then hold down the shift key and select the right arm IK, two are not selected.

I think it works in the Clip Editor, but I want to select it in the scene window. There are so many items in ClipEditor that it's cumbersome to select and it's very stressful every time the selection activation is cancelled.

You need to hold CTRL to add a bone to the selection. Holding SHIFT is going to select all child bones instead. I highly recommend to use the scene view for selecting, as like you've mentioned it gives a nicer overview of all the bones than the clip editor. By default, the selection between the clip editor and the scene view are synchronized.

Please let me know in case you need any further assistance.

Best regards,

Peter
