Hi all, I'm attempting to do some modifications to vanilla items (Pumpkin pie for example), and what I've done so far is: 1) remove the crafting recipe for the vanilla item and 2) create a new mod item to replace. The only issue I'm having is that the original vanilla item still shows up in creative. Is there a way to remove a vanilla item from creative mode? Alternatively, is there another way I could go about solving this problem? Is it possible to override the hunger/saturation values of a vanilla item? Thanks!
