Tilemap Collider 2D w/ Composite Collider Not Working

I know this is an old post, but I was also trying this today and realized the issue I was having. By default, the composite collider uses “Outlines” for its “Geometry Type” attribute. If you change this to “Polygons”, it may work for you. This seems to fix the issue if the graph wasn’t working properly if the node collider was able to fit entirely within an obstacle.
