3ds Max :: How To Turn Objects Into Clothes For Characters

In short I am Trying to assign or attach an existing 3D models Jacket to a Human Character. I have tried many tutorials on youtube but they are all about garment maker clothes not about existing 3D models clothes.

1st- I have a character model with mesh. The mesh his body including trouser (pants) and shirt. The model is biped rigged so works perfect with *.bip animation.

2nd- I have a good looking jacket. Its a original 3d model not made with garment maker.

I tried to attach the jacket as cloth but the jacket did not stay at position when I runplay bip animation, or when I move the model. It seems the jacket is not attached at all as cloth.

I placed the jacket on the character model correctly at position.Then I clicked the MODIFY button.I select in the “modifier list" “cloth”.In “object properties” of cloth I select jacket as “cloth” with presets as “wool”.Then I click “Use Panel Properties”.At add projects I select the other object. And I press “Add”Then I select “Collision Object”.I press “OK”.It seems that the jacket is not attached to the rest of the character mesh or biped.Even when I press “Simulate Local”it does not attach the jacket to the body it miss shapes the jacket.
