Troubleshoot Items Not Showing Inside the Hollow Block

Verify Items Are Actually Inside

Open the furnace, smoker, or blast furnace interface and confirm that items are in the input slots and fuel is present. The hollow display only shows what's actually stored in the container. If the slots are empty, nothing will appear inside.

Check Your Camera Angle

The interior may be difficult to see from certain angles. Move around the block and look from different directions. Try positioning your camera closer to the hollow block's opening or sides to get a clearer view of the interior contents.

Ensure the Block Is Loaded

If you're far away from the furnace, it may not be actively rendering. Move closer to the workstation so it's within your render distance. Once loaded, the hollow interior and its contents should display properly.

Confirm the Mod Is Active

If furnaces appear solid rather than hollow, the mod may not be properly loaded. Check that the mod is enabled in your mod list and restart your world if needed.
