what's the spawn code

Here you go, I know it isn't the usual look with the name of the in some way in it but it works fine using the mod number as well. I also added the max stack size to the code for you as well.
giveitem "Blueprint'/Game/Mods/784080729/PrimalItemAmmo_Rocket_BC.PrimalItemAmmo_Rocket_BC'" 10 1 false

Oh btw "cheat" in front of "giveitem" should not be needed. I use SP so I don't know if it is different for multi player but I work out the spawn codes for my many mods all the time like ones for Primal Earth foe example. Once you figure out how to do it it really isn't too hard to do it for any mod that doesn't include the codes.

Thanks
