Tutorial: Creating a core-data Mod (Not a Map, just a Mod :)

I’m trying to create a mod that tweaks the construction costs for craftable items, I’ve tried to make the changes quite a few different ways and none have been successful for me so far.

I have my mod set up in its own folder underneath the Mods directory, and have copied all of the GenericMod files over into my new folder. For my test case, I copied the PrimalItemStructure_ThatchWall item into my folder via various methods (including right click and create blueprint based off of this to create a child item, which to me seems the proper way to do it). I tweak the crafting costs to craft the thatch wall in the “Base Crafting Resource Requirements” section, save and compile the blueprint. Nothing shows up in game.

My next attempt was I added an engram blueprint override so that the engram points to my new overridden thatch wall using the PrimalGameData_BP blueprint and that hasn’t worked either.

I’m able to “see” and play my mod in the game without any problems, but none of the changes I’ve tried to make have been showing up in game at all.

Where am I goofing up?
