How to Toggle Invisible Item Frames
Making Item Frames Invisible
Round's Invisible Frames Mod adds a simple toggle for hiding item frames without breaking them or removing the items inside. To use it, look at an item frame and hold your sneak key while right-clicking it. The frame will switch between its normal visible state and an invisible state.
When a frame is invisible, the item it holds stays displayed exactly where it was. This lets you show off maps, tools, or decorative items on a wall as if they were floating in place, without the wooden frame around them. Sneak and right-click the same frame again to bring it back to normal.
The mod only affects item frames, so it won't change how other blocks or entities behave. Because the toggle is tied to sneaking, a normal right-click still rotates the item inside the frame as usual, so you can keep adjusting your display without accidentally hiding it.
