I swear I tried that this morning, I could get those options for the collision polygon, but not for the origin point.
It took me the week to get all the animations imported, layered and synced up. Right now they have the default origin point on everything.
I had an idea though, instead of changing the animations, I think I'll add a new empty sprite to the character container and attach the pathfinding to that, then pin the rest of the character layers to the new sprite, but offset the pin point. Should have the same effect as moving the origin of all the artwork, without having to move the origin.
