Anyone?

I have even tried changing the world center to all available options and it still appears in wrong direction.

	GameObject obj = (GameObject)Instantiate (MyObjectPrefab.transform, Vector3.zero, MyObjectPrefab.transform.rotation);
						
						obj.transform.parent = hit.collider.gameObject.transform;
						
						obj.transform.position = new Vector3(0.0638326, 0.01016547, 0.6540853);

If you want to keep the sphere position consistent relative to its parent game object, you should probably use transform.localPosition (as opposed to transform.position, which instead sets the position in absolute World coordinates).

Hi,  OK so I changed to localPosition but still weirdness abounds?

What I have done is to move the imagetarget to 0,0,0 and aligned the camera at 0 on the x axis

Oddly the sphere still appears in the wrong place, but now lower rather than left.  I started to dig deeper and fid that my objects are rotated and so now for my sphere the coords are like xz,y.

After trial and error manually ajusting the values in my script I got it to appear right, but still at a a loss at to why the value reported in the editor when the sphere starts does not reset right?

Thanks for you help

The easiest way to understand how the axis are oriented for an Image target and its children objects is to create an Image Targets in the Unity scene, attach a few objects underneath it (as children) and then check the axis orientation of each game objects starting from the base Image Target object and then navigating down the hierarchy of your objects.

This should hopefully make it more obvious.

AlessandroB thanks!

I now see where I was going all wrong re the coordinate system as not only was I not using localPosition once I started to use it I was in fact using the sphere prefab global position instead of local!

I followed your advice re the testing the relationship of world/local on objects and all is clear ;-)

Great help cheers

Glad to help ;-)
