Hollow Core Voxel Mod FAQ
10 questions players actually ask, answered.
Do I need to do anything special to make my furnace hollow?
No—once the mod is installed, all furnaces, smokers, and blast furnaces are automatically hollow and display their contents. There's no crafting recipe or activation step required.
Why can't I see items inside my hollow furnace?
Make sure you're looking at the furnace from an angle where the hollow interior is visible, not directly at a solid face. If items still don't appear, check that the furnace actually contains items in its inventory slots and that the mod is fully loaded.
Does this mod change how fast furnaces cook?
No—smelting speed, recipes, and all vanilla mechanics remain exactly the same. The mod only changes the visual appearance to show what's already happening inside.
Can I see the fuel burning inside?
Yes, the mod displays burning fuel and flames inside the hollow furnace in real time, matching whatever fuel item you placed in the fuel slot.
Does this work with hoppers and other automation?
Yes—the hollow display syncs with your actual inventory, so items moving through hoppers will appear and disappear inside the hollow block as they're processed.
Will this mod cause lag or performance issues?
The mod adds 3D rendering for furnace interiors, which has minimal impact on most systems, but performance depends on your hardware and how many hollow furnaces are loaded at once.
Does the mod work with modded furnaces or custom blocks?
The mod only adds hollow visuals to vanilla furnaces, smokers, and blast furnaces—it does not automatically work with furnaces added by other mods unless specifically designed to do so.
Can I turn off the hollow display for certain furnaces?
The mod applies to all furnaces globally once installed; there is no per-block toggle to disable the hollow effect for individual furnaces.
What if items look wrong or distorted inside the hollow block?
Try updating your graphics drivers or adjusting your render distance and graphics settings. If the issue persists, check that the mod version is compatible with your Minecraft version.
Does this mod work in multiplayer servers?
Yes, but all players on the server need the mod installed to see the hollow furnaces; players without it will see standard furnace blocks.
