How to enable Trigger on a Mesh Collider

Unity Engine
1

Hey guys,

I want to enable a mesh collider on my water plane but it’s grey’d out on me unless I toggle “Convex”. That seems to give the water a basic square trigger box which seems to defeat the purpose of having a mesh collider that conforms to the exact size/shape of the object.

Any ideas?

Non-convex mesh colliders can’t be triggers in Unity 5, since the updated PhysX doesn’t allow it.

Ah - well that’s good to know. Anyone have any clever ideas on how to craft a collision collider on an object like water that doesn’t have a perfectly square shape?
