Structures and natural resources

Is it possible reduce the range that structures disable natural resources to grow back? We could make some really cool gardens if we were able to build closer to trees/stones.

In the other hand I would like to see grass stop showing through foundations… thats a really annoying glitch, grass/plants inside our houses if we dont build it a reasonable distance from the soil

Yes. Adjust the LandClaimRadiusMultiplier when you start a new game.
Otherwise you’ll need to edit the ini file as this option is not available after starting a new game.

\steamapps\common\Conan Exiles\ConanSandbox\Saved\Config\WindowsNoEditor\ServerSettings.ini

LandClaimRadiusMultiplier=0.100000

Change it to the above value and resources will regrow even if a foundation is touching them.
Make sure to exit the game before you edit configuration files, otherwise the game will overwrite what you do.

Do ‘not’ set the value to absolute zero, that will cause your land claim radius to become infinite and all resource nodes will be removed from the map upon a server restart.
