[Closed] Bones mirroring

Hey guys, I’m trying to make a script that will mirror max bones, without axis flipping, I have several variations, but each of them has its own problems.
This option works well, but it makes the wrong rotation about the X-axis.

Bones_L = selection as Array
Bones_R = #()

   parentBone = undefined

	for b in Bones_L do (
	  newBone = BoneSys.createBone[-b.pos.x,b.pos.y,b.pos.z] [1,1,1] [1,1,1]
	  newBone.name = "newBone"
		
			
	  newBone.dir = b.dir
		
	  if parentbone != undefined then (newBone.parent = parentBone)
	  parentBone = newBone
		
	  append Bones_R newBone
	)
	
	for b in Bones_R do (
		b.realignBoneToChild()
	    b.resetBoneStretch()
	)

this one is working great when i’m testing it on the regular boxes, but with the bones it starts to crash

newBone = BoneSys.createBone[1,0,0] [0,20,0] [0,0,10]
newBone.rotation = quat (random -360 360) (random -360 360) (random -360 360) (random -360 360)

newBone2 = copy newBone
newBone2.rotation = quat newBone.rotation.x -newBone.rotation.y -newBone.rotation.z newBone.rotation.w

I will be grateful for any help!
