Win 8.1 NVIDIA GeForce GTX 780 Ti

Blender 2.79

Animation Nodes ~ Loft Splines
http://animation-nodes-manual.readthedocs.io/en/latest/user_guide/nodes/spline/loft_splines.html

I am able to change the vertex of the loft's source splines and see the generated mesh morph as expected.

I'm also able to use Hooks to move a point of that surface control curve like this demonstration.

Unfortunately the curve moves independently and even offsets after hooking when moving the vertex in edit mode. It actually jumps to a different location in edit mode after being moved by the hook control mesh.
My guess is the animation node should appear in the modifiers and then I can put the order of the hook before it.
Maybe there is really a bug there, or it's super unclear what to do so maybe a toggle is needed somewhere (either in Splines from Object or the Hook modifier) to enable this to be even more procedural by allowing vertex hooks changes/animation to be observed by the animation nodes Loft Spline node.

Sorry, for maintenance of this add-on you'll have to contact the author, because it's not officially maintained / hosted by Blender - it's not in release nor contribution.

You can check if the add-on is a third party one by downloading a developer build of blender and look at the 2.7x/scripts/addons and addons_contrib folders, or check out the https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts under Release and Contrib columns.

Also, before contacting the third party developer of the add-on be sure to:

You have the latest version of the add-on
Follow the instructions for installing and enabling it
Provide some additional information if needed - blender version, a file that produces the error.

Closing as archived.

I posting on Stack Exchange and someone kindly explained the author says it's beyond his ability due to limitations in Blender.
https://blender.stackexchange.com/questions/100628/an-loft-splines-not-observing-vertex-hooks

I don't want to be argumentative here, I'm looking to have this problem rephrased in a way that facilitates the ability in the long run, thanks.

Maybe it is that there is a way to enable addon developers to (in his reposted words) "allow scripts to get the result of curve modifiers in a way that is suitable for AN"?

Please share your thoughts on the possibility and/or likely hood of this being addressed, thanks.

LoftingSplines-02.blend

I've posted an example of this as requested the animation slider will reveal the issue. Further one can still grab the same line in a different location? and see the mesh updating as expected.

Okay well I've made a cross reference issue with the developer as well.
