I have been Hard Surface modeling in Blender for some years now. I have recently been modeling Swords, Axes, Shields, Spears, Bows and Arrows, EXT. Midieval type weapons. I have been delving into Unity, and Unreal in the hopes of making a game with game models. I have been studying 3D Coat to learn to texture and sculpt. 
I bought CC3, iClone7 and the Xchange program. I am just learning how to use them, and watching all of the YT tutorials along with the Tuts that are connected with the opening. 
I want to bring in my props from Blender into CC3. This doesn't seem to be working well. I also think its mostly because I dont know what I am doing with the process.
I wish they had a more in depth course for the CC3/iC7/XChange/CT8 and so forth.
There is nothing on Udemy, or I would have bought it. Is there a course for sale, and I just dont know about it? I am learning from the manual, and the tutorials, but it is sporatic and slow going.
I want to eventually make assets like the weapons for the content store and content market place.
I want to also make a You Tube series about how to do that so some one can follow along from point a to point z without having to pick and choose content and have to figure it out from peace mealing the information.

"This doesn't seem to be working well."

Can you be more specific?  What are your problems and how, exactly are you proceeding?  There really isn't much to it -- you choose Create/Accessory and import your OBJ.  You may have scale/pivot issues but that's mostly the only problems folks get when following that (and thus there isn't much of a tutorial or "course" of the process -- takes about 60 seconds).

Reallusion Wiki might be helpful in answering those questions. (It supposes to!)
This is the general creation pipeline for character assets including clothes, shoes, hair, and accessory.

So, Yes Mike, TY, I was trying to import them and not Create Asset button them. So now I have been able to bring them in.

There are a few ways to get props saved into CC so they can be added to any character as accessories.
You can save the character and the models you add as an fbx file that can directly be loaded into CC. This works well for clothes but accessories I have trouble with sometimes so I do accessories this way.
Not saying this is the best way to do it. All I can say is this is how I prefer to do accessories for CC or iClone. Also easy to set the item attached to a character or just sitting in the scene somewhere without being attached to a character. Anyway, here is how I do it

I import a CC character into Blender and create what I want. Here its an Egyptian hat that will be an accessory.
 I select just the hat and export it as an fbx file


Then I load the fbx file into iClones 3DXchange. For this object I clicked the Auto smooth to smooth it so it looks nicer. Doing it here usually looks better in iClone than using Blenders Smooth settings because that badly affects the coloring of it in iClone. Much better done in 3DXchange instead
Anyway, finally I export the object and it gets saved as an iProp for use in iClone


Next up I run CC and iClone. Then I add a character into CC and send it to iClone like this. By the way, in all these images I used red squares and arrows to highlight what I am saying.


Now in iclone I load the hat and position it and then attach it to the character. For this I attached it to the characters head so it automatically follows the character head as it moves around in animations.


When all that is completed then I select the character and export him back to CC so I can save the hat in CC so it can easily be added to any character and is automatically attached to that characters head.


When it gets loaded into CC I then select the hat and save it. Then I set the CC image so it looks better and then right click the saved object and click the Capture thumbnail so the saved hats image looks better


Anyway, that's how I do it for accessories.

By the way, things like Clothes I don't do through 3DXchange. Rather I export from blender and import it straight into CC.
I had some people ask me how I do that and I posted it here
Thought I would post it here for you incase it might give you some help with that too?
