In the Pinned discussion called "Ini Settings" above, you can see the settings you need to change... Add them to your GameUserSettings.ini in the Saved folder...

So if your steam is in the default place on a windows system you would go to --->
steamapps - common - ARK - ShooterGame - Saved - Config - WindowsNoEditor....

Inside the "WindowsNoEditor folder you will see your GameUserSettings.ini file...

Open it up in a text editor like Notepad or whatever, and add the ini settings block as posted at the bottom of the page with one space btween the block you copy and paste and whatever is above it...

Here is the relevent info from the Ini Settings discussion above --->
Just change CeilingIsFoundation=false to CeilingIsFoundation=true
----------------------------------------------------------------------------------------------
The default settings

[CastleModifiers]
IsPrimitive=false
CeilingIsFoundation=false
DisableAutoDoors=false
ScaffoldTier=wood
SettlerTier=wood
VillagerTier=stone

In-depth explanation

IsPrimitive accepts true or false. By setting this to true, all original castle tier pieces will have the same damage properties as stone. By default this is set to false and all castle tier pieces will have the same damage properties as metal.

CeilingIsFoundation accepts true or false. True will make ceilings register with the game as a foundation on placement. This means no more "require foundation support" when building long bridges or something like that.
--------------------------------------------------------------------------------------------------

So when you are done it will look like this --->

[CastleModifiers]
IsPrimitive=false
CeilingIsFoundation=true
DisableAutoDoors=false
ScaffoldTier=wood
SettlerTier=wood
VillagerTier=stone

I went into program files Steam, steammapps,common,ark.shotergame,saved,config,windowsnoediter, and added a line [CastleModifiers] ceilinglsfoundition=ture. Saved changed but still does not work. What next?

Assuming you copy and pasted what you wrote here in your reply straight from your GameUserSettings.ini, then number one you spelled " true " wrong, and the capitalization of the words " CeilingIsFoundation " is wrong too, and number two it is not in a line, but a block of text exactly as I posted...

So it would NOT be a line such as this --->
[CastleModifiers] ceilinglsfoundition=ture

But instead would be a block of text such as this --->
[CastleModifiers]
IsPrimitive=false
CeilingIsFoundation=true
DisableAutoDoors=false
ScaffoldTier=wood
SettlerTier=wood
VillagerTier=stone

Also I have no clue if just using part of the block of text will work or not... So instead of just using the part of the block of text that deals with the ceiling foundations, use the entire thing just to be on the safe side...

Also of note to you should be that it will not change any ceilings that are already placed, so If you are trying to extend off of old Ceilings you placed before you made the changes, then it may be that you need to replace a couple of the old ones before you extend out further...

In a minute or three I will post another reply with what my ini looks like from the bottom few lines of the default text and into a few of the ini changes I used for various Mods, CKF included...

If your ini changes look like mine, and it still doesn't work, then I dont know what to tell you other than you may want to uninstall and reinstall the Mod, because it works on my end last time I built anything with the Original CKF a few days ago...

One minute and I will post part of my ini for ya...

So here is a part of the bottom of my GameUserSettings.ini... here under the Builders Helmet Text Block is the CKF Text block and you can see exactly how the CKF changes should look...

You seem to be missing some stuff...
Underneath that last block of text you posted -->

[/script/engine.gamesession]
MaxPlayers=70

Underneath that there should be a server settings block of text that is fairly large, then a player info block, then a GameprimalearthCoreBlueprintsTestGameMode block, and then under that should be the CKF Block of text which you dont even have...

So you can see clearly that yours looks nothing like mine right???
Get it right and it will work...

You can see that you did not even put the CKF Ini text block in there...
Either that or you did not post the whole GUS ini...

This block here --->

[CastleModifiers]
IsPrimitive=false
CeilingIsFoundation=true
DisableAutoDoors=false
ScaffoldTier=wood
SettlerTier=wood
VillagerTier=stone

Is not in what you posted... How do you expect it to work if you dont put it in there???
Put that block of text in your ini and it will work...
I dont know how to say it any plainer than that...

You are also missing some other blocks of text... I would look into that if I were you...
What you posted is not complete...

Just to sum it up...

There aren't any magical Ini fairies that are going to come in riding on flying Ini unicorns and put that block of text in your Ini whilst you dream of long bridges made with ceiling tiles that span across great canyons in Ark ...

You actually have to copy and paste that block of text in there yourself...
And then you have to click the "Save" button on that very same Ini after you make the changes too...

Other wise it just wont work...
And dont forget to save a copy of that Ini BEFORE you change it so you will have a clean backup...

OK I am running Ark Server Manager so does each map where your files are saved need to have this in them? I don't see a \WindowsNoEditor in them.

I've never used Ark Server manager so I have no clue...

But if you are doing all that I bet you have Discord...
So get on the CKF Discord channel and let the big dogs help you...

I'm a little dog compared to the Modding masters over there :-)
They can get ya straightened out quick...
