Sorted it now

How did you set it to max weight of 2000?

I put this into my gameusersettings.ini

[Builders Helmet]
Max Weight=4000

You can change the number to get higer or lower amount of weight when you put the helmet on

Mine won't work

I've placed [Builders Helmet]
MaxWeight=2000 in the GameUserSettings.ini, however, it is still not working, can anyone help?

so you guys need help with weight?
