Cloth modifier either keeps intersecting or doesn't work at all

[miraan.ahmad3AMKP]

I'm somewhat new to 3ds max and I've used the cloth modifier once and it had worked. However, now I'm having a lot of trouble with the cloth modifier. If I try to place a plane as a cloth on a box, the edges of the box tear through the cloth and the cloth becomes wavy. This happens even though I've given it a good amount of polygons. And in some cases the plane doesn't even rest on the box and keeps falling down. (The plane is selected as a cotton cloth, and the box as a collision object, and all the settings are default)
I've provided the photos of the problems I'm facing. I hope someone can help me out with this. I would really appreciate it.

Hi @miraan.ahmad3AMKP 

Regarding cases when the plane goes right through the box, this shouldn't happen if you click on "Simulate Local (damped)".  It does happen when you click "Simulate Local" because the effect of gravity is too fast for the max cloth simulation to handle for a given resolution of the cloth mesh.  That is the purpose of the "Simulate Local (damped)" option -- to slow down (ie., damp the effect of) gravity.   You could also change the Gravity setting to a low number, like say -300, and it would have a similar effect to "Simulate Local (damped)".

Regarding the corners poking through the mesh, you can either increase the resolution of the cloth mesh or increase the offset value of the box collision object to correct this.  The cloth simulation needs enough mesh resolution to wrap the cloth around the sharp corners of the box.  Cranking up the cloth mesh resolution will slow the simulation but will make a more natural result.  Increasing the offset of the box collision object forces the cloth mesh away from the sharp corners. 

Hope this is clear.

In addition to @10DSpace 's advice you can tweak the Simulation Parameters.
