Z point of terrain

Hi, I can't seem to find the new trigger for finding the exact Z point of the terrain. I know theres the cliff height one but I need the exact level. Thank you.

I think I've found it now (after taking the time to search), hehe. :)

Hmmm there's also an integer Environment - Terrain variance. What does this do?

Terrain variance finally allows you to move a camera with a unit when he goes up hills (set camera height = Z of point (position of (unit)))

And ant is right, use "terrain variance" for your trigger
