Go to the BP_PlayerInventory and create a new variable called PlayerInventoryDetails and set its Variable Type to S_ContainerDetails and tick on Instance Editable. Then Compile and set its Default Value to the settings shown below.

Next create a new variable called PlayerCraftingType and set its Variable Type to E_CraftingType and tick on Instance Editable. Then compile and set the Default Value to Player.

Then copy the video below inside the BP_PlayerInventory in the Begin Play collapsed node.

If you are using an older version of Survival Game Kit V2 and your code doesn’t look like the code in the video just copy the video and put the Set Inventory Details between the Event Begin Play and Parent: Begin Play nodes.

To change the player inventory pocket settings you now use the PlayerInventoryDetails setting in the BP_PlayerInventory Class Defaults.
