I wanted to know how I would approach this making a game that is top down 2d but in a 3d platform. Here is an example of Enter the Gungeon: https://twitter.com/dodgerollgames/status/593625936131653632?lang=en How would I do this to get the 2d look for tilemap? Thanks for any reply’s ( if I even get any )

You just have to set it to true and it will make your game appear to be flat.
