Why is my server different from other people's servers?

为什么别人的建造模式，可以用红铁造墙，而我的只能用木板和铁造墙？
Why do other people build models that use red iron to make walls, and what I can do is to build walls with boards and iron

 

Those thinks are calling mods you can downlaod then from the steamworkshop on the page from hurtworld
then you've to add the loadmod number inside from your autoexec.cfg like this loadmod 794032480
pres save and restart your server when the restart is done you got the whole mod insite of your server
but be warned not all of those mods are working it mid be letting your server crashing
