So, after i made a simple system of pathfinding and navigation2d with a navpolyinstance which detects other collision polygons, when moving around i get this in the output console
“convex partition failed”
What does that mean?
If you need more information about how to recreate this or the script, etc, comment here please
Help me… Thanks
