I'm having some weird bug, like half of my models are hovering ingame while in ZE they're just fine. Did anyone ever had such a problem and is there some kind of ZE function that could have done this?
I guess I could just put the object a bit into the ground, I'm just wondering if there's a way to fix it.

i have had this problem before, you could either just delete them then re-place, or open the .wld file and manually make sure their heights are correct.

This is a quirk of ZE, a model's placed height is only 100% correct compared to other models. Apparent terrain height relative to models is always a little higher in ZE than in-game.

Try clicking the Ground Object button- i just noticed it, it might work.

Neat idea but that doesn't work either. I tried it already.
Well, I "fixed" it by placing the objects into the ground now anyway.
