Hi
Im completely new to this but I have been messing around with this for a few hours so I thought I might ask for some advice.
Following your tutorials is great but a bit hard sometimes since some of them are old and major changes have been made since then, half of this is probably due to me not knowing the Unreal engine editor either 
I have started with a few small goals to try and get going.
First I want to get a simple mesh with some hills and walleys setup.
I follow that part of your tutorial but when I start the pawns float down to the base grid as soon as I move them.
Anyone know what I might have missed?
Second question is for the pawns themselves, is there anything special I need to think about when introducing my own units?
Plan here is to copy one of your units and change the mesh to a simple box like vehicle while disabling animations.
