Id say if your looking to do high end stuff then maybe take a look at iray render, think its around 100 dollars??? 
But you get a more polished look. Much much better than the standard render in iclone

Or you can look into Unreal. Thats free but has a drawback where if u buy reallusion marketplace items, you HAVE TO BUY EXPORT LICENSE and these are a lot more expensive.

It is possible to export a character from CC3 with a pose as an .obj file if Stager can accept that format.



Another option would be to render a .PNG with transparent background. Open the Project Settings panel from Edit > Project Settings:



Scroll down to 2D Background make sure that the Background colour is set to Black and that "Activate Image" is not selected. Then select Render > Render Image and set the resolution for the file.

I really appreciate your reply and information. Do you know if I can export an expendable PNG on the free trial version of Iclone? If not can you point me to a link that tells how much it would cost after the trial version is over because I only have a few days left? I have tried to look for a price but cannot find it. 

What you would do is set up your scene to your liking in iClone. You can use multiple characters and scene props; the limit is determined by your system.

You can then add and adjust lighting, just as you would on a real-life stage.

Once you're stratified you can then render the scene to an image (JPG, BMP, PNG, TGA) or, in case of animation to a video format.

Others have used iClone for book covers and even graphic novels.

I have a few free days left for IClone. Can I create a scene like mentioned before and export it as a PNG for Photoshop? I am not designing for an animation or game, it is a design for a book cover. 

Yes, you can do these and much more with iClone. (It's paid), you can also do it with the Unreal Engine, which is free.
However, as far as I can see strager remotely is a somewhat simple program.
So for other programs you will need to learn a little more.
As a learning line, iClone is a little easier.
You may need to spend a little more time learning the Unreal Engine.
But if you plan to deal with these things all the time, it would be better to start somewhere.
Strager is a complete waste of time.
You can check out the videos of the programs I mentioned.

Can IClone be a stager too? Meaning you can import multiple 3d items liked a Pinnace and 7 different characters... and export them all together as a scene PNG?

I can't comment because I don't have Adobe Strager program, but many people are not satisfied with Adobe Strager.
Adobe Stranger is more of a starter program. It is not a professional program.
Frankly, I can recommend you to use iClone or Unreal engine instead.
After all, you are likely to experience these problems every time.

Yes, I got it to work, but when I import character into Adobe Stager, they are still all white. See the image below. Is there still something I am doing wrong?
