Could I make a cloth physics interact with a cube collider in Unity5?

I am currently making a horror game in where I have a cloth moving around as a ghost around the player.
Once the player looks directly at the cloth gameobject I add a rigidbody to the cloth gameobject to make it fall to the floor in a very creepy fashion.
However, when the cloth gameobject interacts with the plane gameobject (the floor in the scene) the cloth falls through the floor.
I am unsure how to handle this the cloth gameobject collider only allows for sphere and capsule colliders.

Any thoughts on how to solve this problem?

Have you solved this problem? i have the same problem and i can’t find a solution.

I had to use an asset for this.
