Enabling the Dragon Totem Texture and Fixing Pack Load Order
Activating the Pack in Options
Open the pause menu, select Options, and click Resource Packs. Locate the Dragon Totem of Undying Resource Pack in the left Available column. Hover over its icon and click the right-facing arrow to move it into the Selected column on the right. Once loaded, every vanilla Totem of Undying in your world changes from the standard gold and green face into a bright red dragon.
Resolving Texture Conflicts
If you use other survival gear packs or full fantasy texture overhauls, your totems might still show another design if that pack loads higher in your list. Minecraft applies resource packs from bottom to top, giving higher packs priority. Open Options > Resource Packs again and find the Dragon Totem pack in the right column. Click the up arrow on its icon until it sits above any other item or UI resource packs. Click Done to refresh your textures, then check your inventory or off-hand to confirm the winged red beast is visible.
