I would like to set all the loot of my server to 3x, barrels, crates, trees, rocks, etc... How can I do that?

Read the over view, there's extensive explanations for usages of the commands.

Can you maybe just answer the question?  There are those of us who are not tech savvy...i have read the over view, and see no option or command to do everything all at once.  SO, are we missing something, or does it not exist. 

You mean there are so many of you lazy enough to not read the caringly written overview?

It's there for a reason. Read it. Reading gets you places.

Sorry Ryan, I read the post, I always do, but I missed that information but when you first replied to me, I read again and saw it.
Thank you!
