Enable 3D Item Models in Your World

Prerequisites

Before 3D items appear, you need both the base Fusion mod and this resource pack installed. The resource pack alone won't work—it depends on the mod to function.

Activating the Pack

1. Open your world or create a new one with the Fusion mod enabled

2. Pause the game and go to Settings → Resource Packs

3. Find "Fusion 3D Items" in the available packs list

4. Click the arrow to move it into the active packs section (right side)

5. Move it above any conflicting packs that also modify item models

6. Close settings and reload your world if needed

Verify It's Working

Pick up a door, sign, torch, or cauldron. If you see thick, solid shapes with depth instead of flat 2D items, the pack is active. Items in your hand and on the ground should both display the 3D models. If items still look flat, check that the resource pack is positioned above other packs in the list and that the Fusion mod itself is loaded.
