On custom bone shape

go to ‘Pose mode’ -> ’ Bone properity’ and ‘Viewport Display’, clicked ‘custom object’ and chose the each objects: kneeIK.L, kneeIK.R

but it doesn’t seem they are not synchronize each other cuz the scale of shape is different and of rotation.

I adjusted the bone size on ‘Viewport Display’ but I want to match the same size and shape.

So I edited the object in ‘Edit mode’ like scaling up and down, rotating left and right. Custom bones don’t move at all.

what’s the problem?

Did you try applying rotation and scale?

Ah~! the problem is solved~
Thank you so much
