I make a 2.5D first person game like Doom, Duke Nukem 3D, and Daggerfall used to be. I'm new to Unity and game development in general, so I'm sorry if this seems obvious to some people.
What I want is to have the 2D sprites of the trees to billboard smoothly in the same way they did in the old games. Take a look at this video to understand what I mean: https://www.youtube.com/watch?v=xPwGXf8y6XA&t=277s
I've already tried the proposed solution at http://wiki.unity3d.com/index.php?title=CameraFacingBillboard and it doesn't work the way I want, it's uncanny and off-putting the way it works.
Please help me.
