Almost sure this isn't possible.. Although maybe I'm wrong; Can you remove the glow from a netherstar, or is it bound to the item so to speak?
Desle If you hack around with NMS you can probably remove the glow effect. I'm not sure though, maybe someone else has managed to do it before and can help you out.
I'm fairly certain that it's client side, as I'm pretty sure you can customize the glow when making a resource pack.
xTrollxDudex Quaro Quantum64 Alright.. now I didin't mess it up this time; This doesn't work; Code:java @Override public void onEnable() { Bukkit.getPlayer("Desle").getInventory().addItem(removeAttributes(Bukkit.getPlayer("Desle").getItemInHand())); } public static ItemStack removeAttributes(ItemStack item){ net.minecraft.server.v1_7_R1.ItemStack nmsStack = CraftItemStack.asNMSCopy(item); NBTTagCompound tag; if (!nmsStack.hasTag()){ tag = new NBTTagCompound(); nmsStack.setTag(tag); } else { tag = nmsStack.getTag(); } NBTTagList am = new NBTTagList(); tag.set("ench", am); nmsStack.setTag(tag); return CraftItemStack.asCraftMirror(nmsStack); }
