Hi Leo,

is there still a problem with displaying the camera render textures or is the input/placement mechanics not working properly? I just tried out the code for the scene picking controller and I found that it can't be working. The RawImage's rect position will not deliver the world position but the local position, which was wrong for the calculation. The following adjustments to the code did the trick for me:

      Vector3[] v = new Vector3[4];
      ARCameraRawImage.rectTransform.GetWorldCorners(v);

      adjustedPosition.x = (Input.mousePosition.x - v[0].x) * (Screen.width / (v[3].x - v[0].x));
      adjustedPosition.y = (Input.mousePosition.y - v[0].y) * (Screen.height / (v[1].y - v[0].y));
      adjustedPosition.z = Input.mousePosition.z;

Note: ARCameraRawImage is actually ARCameraRT from before (which was not well named back then).

Here is a link to the GetWorldCorners() method documentation from Unity. This method delivers all 4 world corners for any UI element and this then can be used to properly do the adjustment calculations (which formerly delivered wrong results and therefore wrong positioning).

Kind regards,

Gökhan
