So I've created a mesh in 3DS Max, assigned materials to it, created collision as per this tutorial, then processed it through elric, then added it to the world space in the CK. Everything looks and works fine with one exception, when ingame I am unable to place a workshop/settlement item on top of it. I've been messing around with the settings in CK and 3DS for a few hours now and I can't figure out how to make this happen. If anyone has any tips or knows how to fix this it'd be much appreciated.
