This tools helps a ton. Thank you! It didn't take much rewriting to get it running on Unity 2017.4 LTS (hardest part was figuring out the older way of baking).

Anyhow, first thing I noticed is that it doesn't observe the rotation value of the colliders (at least, not in my version, and I haven't checked the code to see if it should be there). I don't need this at the moment so just noting that it would be nice to have. CapsuleCollider2D might also be nice to have but I go back and forth as to whether or not I might ever use it for walls.

Complex polygon support, thankfully, works wonderfully! That's something that Navigation2D can't seem to do. I'm not even sure A* Pathfinding Project Pro can do it properly.
