When the new 2D physics system came out, I got all excited to create 2.5D games: out-of-the-box 2D physics with 3D meshes! No more big 2D physics asset store packages to download, now I can just do this with nothing but basic Unity!
The only issue I had was this: you can create a meshcollider from a mesh, and you can create a polygon collider from a sprite, but you can’t create a polygon collider from a 3D mesh. So every asset had to be manually processed by adding a polygon collider, adjusting the points, etc etc.
So after processing 5 or so props I grew tired of this, and started writing a tool that does this for me: a 2.5D polygon collider tool. It creates a cross section of your mesh (visualized by a movable plane) and makes a polygon out of it.
This is my first asset I’ve ever put on the store. If you have any comments, suggestions or ideas for extra features, let me know!
