Preventing nodes from connecting diagonally when shared orthogonal nodes are unwalkable

Beginner Questions
1

In green is the path generated by the Seeker component. Red is unwalkable nodes. Towards the end of the path, it cuts diagonally between two unwalkable nodes. However, this shouldn’t be possible. So, I’m guessing I have some setting all wrong. I need to know how to prevent such nodes from connecting diagonally.

I have a custom GraphModifier component that sets the nodes to be unwalkable OnPostScan(). So, no physics is being used to determine the walkability of nodes.

Hi

I suspect that you do not recalculate the node connections after you have changed their walkability.

Hey, you were right. I didn’t realize I had to call it. Must’ve missed that part in the documentation. Thanks a tonne! It works great now.
