Resources in the inventory are created through sending a set of Packets that is very similiar to those which are send for creating other items in the Inventory.
The main difference is that resources are not created through CREO Packets but that for Resource Creation ONCR Packets are used.

The creation process begins with an Object Init Packet and an Object Link packet, the main data is send through an ONCR 3 and an ONCR 6 packet and the creation process is ended through an ONCR8, ONCR9, an object finish and an Posture update Packet.

there are still some parts of the ONCR 3 and 6 Packets which are not figured out yet, though as far as I can see they are hopefully not that important.

Please note that -like with everything- these packets can be send standalone in an 00 09 or in the pack as an 00 19. to make this a bit clearer I seperate them as single packets.
I did not include the headers though (00 09 wx yz and crc at the end) because thats getting redundant.

The object init Packet contains the ID of the newly created -(resource) Item, the crc of the item to be displayed and its location and orientation in the world should it not happen to be in the inventory / backpack.

The SMSG_OBJ_LINK packet links the item to the container where its to be created in. This is either a backpack, an inventory, and probably a hopper or house, too.
