I have a multi-story proc gen dungeon, and how can i only detect "Ground" layer as things walkable?

I have a proc gen dungeon. it spawns “rooms” and connects them procedurally. but i have stairs and doors making the dungeon go up and down height wise. The tool doesnt seem to detect stairs all that well. (flat box rather than angled) is this a simple fix because i cant find out. I’ve messed with the ray length but it doesnt fix my issues (because of the mutli-story dungeon).

And this little problem :’(

Hi

It looks like you are using a grid graph with a huge node size. Try to reduce your node size to get better resolution.

Also note that for the grid graph to handle multi-layered worlds, you will need to use the Layered Grid Graph (available in the pro version).
