Collider issues when models used within Unity

Hi, was hoping somebody could help shed some light on this issue. 

It seems that when I import a model into Unity (in this case a sort of mini-golf course), no matter the export settings of the model, there are invisible walls between all of the tiles. Even if I merge the objects within asset forge and use a mesh collider it still seems to register microscopic gaps between each tile that cause objects to behave strangely when transitioning from one tile to the other (may leap into the air or stop completely for example). 

Sorry if this sounds more like a Unity help request but I believe it may be caused by a slight bug with the merged tiles that seem to maintain small gaps even when they aren't supposed to.

That's definitely a Unity thing. You need to change the "Default Contact Offset" setting in Edit > Project Settings > Physics. You may also benefit by changing the Default Max Deprenetration Velocity setting as well.
