Is there a collider with a plane shape?

Like a cuboid while the height approaches 0 infinitely.

This sounds like Collider::half_space, which can be used for e.g. an infinite ground plane.

But its area is infinite. If I want a finite plane, should I still use the cuboid but set its height to 0.001 manually?

[Jondolf]

Ah sorry, I read your original message wrong. Yeah for a finite plane it's probably simplest to just use a thin cuboid. A convex hull of the four vertices of the plane could also work.
