Describe the bug
Raycasts sometimes tunnel through polygon shapes with the "Solids" build mode.

To Reproduce
I've attached a project demonstrating the behavior. Simply move the mouse around to see the difference between raycasting against solids vs segments.

Expected behavior
Raycasts against polygons with build_mode = BUILD_SOLIDS should behave approximately the same as raycasts against polygons with build_mode = BUILD_SEGMENTS.

Screenshots
Blue = Raycast result against segments
Orange = Raycast result against solids
raycast_error

Environment

  • OS: Windows
  • Version v0.5.1
  • Godot Version v4.2.1

My guess here is that it finds more than one result and it doesnt send the closest one. Looking into it.
