Remember variable on server restart

Hello together,

I am working on my first mod for Ark, till know it was a lot of new stuff, but after hours of hours it worked.

I have an blueprint ingame I want to change the material via the radial menu. This is working.
After some research it is still working after I log out and in again, it remebers the changed material.
But when i restart the server, all placed objects are changed back to the default material.

Can anyone please point me in the right direction, how or where i need to save this variable,
so the object remembers the material over an server restart.

Select your variable and in the details there is a “SaveGame” checkbox. Depending on how your are changing materials, you may need to add a check on ebp to set it back to the last color
