Properties required to use a nav mesh with Paper2D tilemaps

I’m trying to use a nav mesh bounds volume with a Paper2D tilemap but I can’t find a way to make it work.
What properties should be set on the tilemap and/or the nav mesh bounds volume to get it working?

I was able to work around this by setting the collision thickness in the TileMap editor to 500. There might be a better solution.

Yes, you definitely need to give it a big enough thickness. Cheers
