This is the same in both Hitfilm 3 Pro and Hitfilm 2 Express.
Is this intended behaviour?
Set 2 points in 3D space (A and and set two keyframes and a small (200x200) 3D plane's position to that of Point A, then a few seconds later on the timeline: that of Point B. Then set the Anchor point of the Plane to -100,100,0 so its top left corner is 'attached' to point A at the start.
Setting the plane's Layer Properties > Alignment to "Along Motion Path" (any of X, Y or Z), the alignment of the plane seems to rotate/orientate around a different position than the Anchor Point (presumably because it is not 0,0) and so the Anchor Point and that plane are offset from each other when it moves.
1) How do you make it rotate around the actual Anchor Point?
2) During the movement from point A to B, although the plane and the orientation arrows do face in the new direction, the angles are not updated on the console (neither Orientation or Rotation) to show what the new angles actually are, and once it moves past the second keyframe, rather than maintaining the last angle, it resets back to 'facing the camera/forward'. So it's like the alignment doesn't stick, although other rotations/orientations that do affect the console (such as keyframing between different values) does maintain the last angle.
So, trying to parent to this plane, so that something remains a set distance in front of the plane (3D text hovering in front of a wall) as it moves between the two points doesn't work, and it remains facing forward. How can I 'inherit' the plane's new orientation while is is moving to achieve this?
Adding a third 3D point after the 2nd is interesting as it follows a nice curved path though.
So, not sure if it's intended behaviour or not, but if it is: why is it better to work as it does than to update the angles as they change, and how do you 'get them out' for other objects to use?
