3rdpersoncharacter only shows up ( body) at TOP of terrain

AS the picture indicates, pressing play from here, does not snap 3rd person char. to terrain for play, whereby it only works at THE very top of the terrain project, literally the very top of terrain, as Z=380 .

Weird,never seen anything like this before.
I had yes brought terrain in from another engine as a test, could this have something to do with it, and if so how do I fix this mess ?

ty

OK, I fixed it, odd tho the fix was!
I don’t recall turning on world settings as I was along way from that, but turns out I had to disable something in world settings, tho going back i’m unable to recreate problem LOL\

shrug–oh well its working anyway.
