There is no engrams, use the default item names from the game.
You probably already know, but here it is anyway: https://ark.gamepedia.com/Item_IDs

Anyways I discovered myself.
Metal Ingot
cheat giveitem "Blueprint'/Game/Mods/Stackforhumans/primalearth/resources/PrimalItemResource_MetalIngot_Child.PrimalItemResource_MetalIngot_Child'" 1 0 0

Other thing, Structures from S+ Walls, Large Wall, etc. They have a high weight. All resources you can pick a lot of them, but when you craft them to s+ Structures you will not be able to walk again.

You dont need to directly giveitem of the items in this mod, because they are all remapped.
When you give yourself a vanilla wall for ex, you will receive the wall from this mod, unless using it with another stack mod.

S+ Structures have their own weights and stack sizes, it would be a very hard task to support every structure of every mod out there. This is for vanilla structures, resources etc only, and they are already above 600 :) Cumps aí para o Brazil
