First of all: I am using your mods and they are fantastic!!!
Here some suggestions to improve building in ark: Im trying to describe it as good as i can ;)

Im building beneath a ledge (it seems like a little cave) and im trying to close it. Im using normal metal structures. Everything works great but the edges. With builders helmet most of the edges are closable (pressing p) but not all of them. It seems like they are closable, when the wall extends only the half into the the rock. If the wall or fundation extends more than half into the rock it doesnt work. Pressing p doesnt work. Im getting a message that i cant place it.
So i was locking for a solution. I noticed using cheat ghost most of the gaps are closable when im going into the enviroment (rock), so from that point of view the wall or fundation extends only the half into the world :)
That helps in 95% of all cases. The oher 5% gaps are unclosable (cant place structure here...).
I tryed everything... If u want more information about that you can contact me ;)

Ohner improvement: Can you influence the maximum building height? That would be incedible cool. Didnt find a way to increase it.
