Invisible Furniture is an add-on for Fallout 4 that allows you to mark locations for your settlements to perform various tasks, like dancing or doing push-ups.

It is very easy to install, you just need to download the file and run it. The first time you run the mod, you will be prompted to install it or not, and you will be given a list of available animations. If you want to install the animation, you just need to click on the download button, and it will be installed into the game.

After installing the animation, you will be given the option to perform the animation during your free time, or in the workshop.
