Adding an Engram to Smithy

Okay so basically I am just starting out with modding Ark, and I personally have downloaded a fair amount of mods, and I was wondering exactly how to add an Engram to a Smithy, so I duplicated a Stone Hatchet, modifying the base stats and what not, I want to make it craftable only in a Smithy, so far all I can get it to do is show up in my Inventory Crafting List, but it requires a smithy to craft, I have created a child of the AnvilBench inventory BP, and added a default inventory item and default engram entry, adding the custom item and 1 as the number on the default engram entry slot. What else am I missing? Do I have to recreate the entire smithy, if so how do I do that without creating a whole new smithy, and without it affecting another persons mod.

Thanks in advanced
Regards

Additional Structure Engrams

Don’t fiddle with the inventory unless you want to remap the smithy and have stacking issues with other mods.

And don’t “give blueprint to players inventory” unless you want to confuse 95% of the player base, they are scared to death of reading, and will flood your mod with “i dun work dis item”

I would not recommend using “Additional Structure Engrams” though. It unfortunately doesn’t really work. I’ve used it for a new Mortar recipe. The recipe showed up at the beginning, after the next server restart (or in my case game restart, since I’m playing singleplayer), the recipe was gone and I had to build a new Mortar so it shows up again (until next restart).
I’ve checked with people in the discord chat and it was confirmed that “Additional Structure Engrams” have this problem unfortunately.

Any solutions?

I wrote a tutorial about that here: New Engrams for existing Structures - ARK Modding Wiki

I’m stuck here

I’ve created a new level in theislandsubmaps, but am lost on the next portion could you help?
