Hey guys,

Anyone can tell me, why the Item dosnt enable for crafting!?
All Other Items work fine

And all has the same settings…

If you can’t see or craft an item with the exact same settings, it may have a parent that is not craftable, and at runtime the game will remove it from the craft list. This can happen if you make a child of some items like feces.

thx for helping…
i replaced all my Blueprints from my Test Folder to the Original
Know its work…
