Hello All,
Since I'm very new to iClone, Character Creator, 3DXchange I'm doing my best to learn from Video Tutorials and mostly from experimenting by doing stuff.
The next issue I'm trying to understand is related to cloth in iClone, Hopefully I can get some help in this:

What I'm trying to do:
So I have my CC character finished and I'm happy with it, now it's time to put some clothes on it!
For what I want to accomplish, forget about the library and presets that came with CC + Essentials (which are amazing BTW), I want to go in a more dynamic way and CREATE MY OWN cloth designs for my character.
I can model the basic shape of the cloth based on the character's final shape, bring it to 3DXchange... but here starts the confusion of what's next?


Things I'm not sure how they are working and if possible to accomplish by myself in iClone:
If I drag and drop any of the CC library's cloth on the character it's calculating the best to fit to the character which seems like MAGIC! but as I described above I want to make my own Cloth Design and use it on my character, let's say a Hoodie for example.

1 - Is there a way to make this Hoodie which I can model by myself and export from 3DXchange to do this "MAGIC automatic fit" to all the CC characters?   I would like to understand how it works and if possible it will be great to learn!

2 - If it's not possible to do the automatic-fit from my very own Cloth Model, How can I still make it work on a specific character? how do I make the hoodie to not fall from the character.
I'm guessing it's up to the weight maps inside iClone based on the UV mapping (photoshop for black & white) but I still don't understand exactly the all process before I even get to the setup of the weights...

3 - But what makes part of the cloth to "fall down" and how do I "stick" other part of the cloth to the character's body?
Do I make the cloth as an extra part of the character inside 3DXchange first?  do I need to parent it somehow?
I'll be happy to understand how to make this from START to FINISH, a good explanation or a video tutorial to show how I can make my very own Cloth Model from 3DXchange to.... what's next, until it's actually works in iClone.

As you can see, even though I understand the basics of clothing and weight maps, I'm still confused about the all process from the beginning.
This may be simple for you guys who already have experienced with this so I would love to get any help to understand it so I'll be able to design my very own not-typical clothing for my characters.

Sorry about my bad English and thanks ahead! :)
