Terrain height at map point2D ?

[Smokeynz]

I use something similar in my develpment I am working on, where I use a trigger point reference to activate the process, then within the Ontrigger I use the 2D pos location realtive to the trigger location. I only needed the 2D at this point, but was thinking about 3D aswell
There is 3D like the 2D which contains the z axis.

If you use the visual express you can load the specific clod syntax.
