Hey Gabriel,
You may get answer you’re looking for here:
That project uses Paper 2D, but this would work with any project if that’s what you’re looking to achieve. Keep in mind that animation for your character will act as if it is in air, and you may need to adjust settings for your animations.
Hope that helps! If not, please describe with more detail what type of project you’re trying to create and whether you’re using Paper 2D.
