Enable 3D Items in Your Inventory
Check Your Resource Pack is Active
Once installed, the 3D Vanilla Items pack needs to be enabled in your world settings. Open your world or create a new one, then access the resource pack menu.
Activate the Pack
1. In the main menu, go to Options → Resource Packs
2. Look for "3D Vanilla Items" in the available packs list on the left
3. Click the arrow icon to move it to the Active section on the right
4. Close the menu and return to your world
Your inventory items should now display as thick 3D models instead of flat sprites. If items still appear flat, try closing and reopening your inventory. You may need to restart the game for all textures to load properly.
Verify It's Working
Pick up any item—food, tools, or materials—and look at it in your inventory or when holding it. Items should have visible depth and thickness. Dropped items on the ground will also appear chunky and three-dimensional.
