Material Types

All materials come from your inventory. The crafting system recognises four resource types:

Type Examples Fish Tuna Fish, Parrot Fish, Minnow Fish, Blue Marlin, Arapaima, Great White Shark, and many more caught while fishing Ore Bronze Ore, Copper Ore, Silver Ore, Gold Ore, Mythril Ore, Platinum Ore, Emerald Ore Plant / Byproduct Wheat Plant, Potato Plant, Rice Plant, Sugar Cane, Cranberries, Raspberries, Goji Berries, Acai Berries, Mutated Plant; mutant byproducts: Mutated Slug, Skull, Spine, Mutant Brain Generic Junk, Plastic, Microchip, Carbon, Gold (gold bars from robbery), Nitric Acid, Fishing Rod

Fish may exist in both your legacy FishingInventory and your regular inventory. The server checks both and combines them — you do not need to move fish between inventories.
