In the application of a property Convex in the MeshCollider component, this function is very useful, but it also has a pit in it
His benefits When you click, he will automatically generate a collider according to the model, which is an irregular collider.
His disadvantage is that when you don’t click Convex, for example, when you have an object in such a position as shown in the figure
When surrounded by MeshCollider, you can't check this object by ray inspection, even if you ignore the MeshCollider object by layer, you can't check it out.
