So, some Player say "it's to expencive" and other ones say "it is too cheap". So everyone can change the costs to build by himself / herself.
You only have to think, what do you want to fill in what it should costs. Enter the Command in your game.ini and everyone will be statisfied.

Here is a list of how the command works (examples are below)

ConfigOverrideItemCraftingCosts= [This is the Command](ItemClassString="PrimalItem_NAMEOFENGRAM_C" [This is the Engram you want to change]
,BaseCraftingResourceRequirements((ResourceItemTypeString="NAMEOFRESOURCE_C" [This is the Resource what it should cost] ,BaseResourceRequirement=AMOUNT [This is how much it should cost]
,bCraftingRequireExactResourceType=false))) [DO NOT change in true]

Example 1 (VERY CHEAP):

The Magic Cake costs only 1x Stone

ConfigOverrideItemCraftingCosts=(ItemClassString="PrimalItemConsumable_Magic_Cake_Converter_C",BaseCraftingResourceRequirements=((ResourceItemTypeString="PrimalItemResource_Stone_C",BaseResourceRequirement=1.0,bCraftingRequireExactResourceType=false)))


Example 2 (VERY EXPENSIVE):

The Magic Cake costs:
1x Artifact Of The Brute
2x Artifact Of The Cunning
3x Artifact Of The Strong

ConfigOverrideItemCraftingCosts=(ItemClassString="PrimalItemConsumable_Magic_Cake_Converter_C",BaseCraftingResourceRequirements=((ResourceItemTypeString="PrimalItemArtifact_12_C",BaseResourceRequirement=1.0,bCraftingRequireExactResourceType=false),(ResourceItemTypeString="PrimalItemArtifact_11_C",BaseResourceRequirement=2.0,bCraftingRequireExactResourceType=false),(ResourceItemTypeString="PrimalItemArtifact_09_C",BaseResourceRequirement=3.0,bCraftingRequireExactResourceType=false)))

Every Resource you will find here:

Use the column "Class Name" for your personally resource.

IMPORTANT

You have to enter the command under

[/script/shootergame.shootergamemode] in your game.ini

If you still have questions or problems, or if you dare to write this command, leave a comment with the raw materials you would like to have.
