Incorrect number of triangle points on collision _testTriangle

[Tricotou]

Hello

@Caner

one submesh had 5 vertices. Therefore eventually in Collider._testTriangle, one point is missing for a triangle

5 vertices is fine as long as triangles are defined on them. Doesn’t mean that necessary a triangle is missing… For example :

That said, indeed the issue comes from topology. Your mesh node0 is only edges, no surface :

Avoiding it solves the issue : Playground

But still, I kinda agree it’s a bug. Best would be that it doesn’t trigger an error, but simply go through.
