jchimin, Yes, cloth will deform over anything that it has been told to collide against, but collision detection is a global setting that will effect how two objects in a secne either penetrate or not. For example, you'll be able to place a telephone on a table, and have it rest precisely on the surface of the table using collision detection globally in the scene. Then you could drape both the phone and the table with a cloth object that would deform around both objects. That deformation would happen regardless of whether collsion detection is on or off globally in the scene. The cloth will be told which objects to collide against, that way you can chose the barest minimum of objects to include in the cloth dynamics processing. Collision detection won't help bad joints. Good joint parms and good polygon placement, and possibly JCMs are the only real way to address that issue. Collision detection will help when you are dressing a Poser scene with props and you want to place objects on top of each other, or beside each other. It may also be helpful with posing, such as showing when a thumb is penetrating a hip.
