Solved Change level and XP of blueprints and remove all default items?

So questions. Can I change the blueprints levels or XP that need to open them? Can I remove all default items that player can craft when they are for first time in the server?
I tried to change level but it didn't worked:

Code:

foreach(ItemBlueprint bp in ItemManager.bpList)
{
    bp.UnlockLevel = 0;
    bp.UnlockPrice = 0;
    bp.userCraftable = false;
    bp.isResearchable = false;
}

 

I thought so. Dammit!

 

That'd make it easy for cheaters though.

 

I think I'm get it. You can change the level and price on the server BUT on client it doesn't change the UI. Because after my experiment (the code in first post) i couldn't buy any blueprint.

 

That'd be possible very well.
