To be clear, you're asking a procedure question about Mixamo on a Flash/Animate forum. You found that the workflow is to create your characters in Mixamo and then work in Fuse to create the animation. That is the process. Dreamweaver and/or Flash/Animate are not going to provide any help in outputting an animation in any medium.
The best place to get information on Mixamo is on the Mixamo forums: Mixamo. There should be plenty of people there who can get you the information that you want.
Not too be rude in way shape or form Robdillion, but here is a little fact check for you, Mixamo and Adobe Fuse, Animate, Dreamweaver and all of them are together, they have formed some sort of partnership, so they are indeed working together, because you have to ask yourself this question, why would a person come to a forum about another software?
There had to be a reason for me to come here, of all places...
All that it would have taken was a few moments to give me the information, in which case, someone already has, because this is not the first forum that I place this post. But thanks anyway.
It can be a little confusing, but this is the Adobe Animate forum. Adobe Animate was previously called Flash Professional. We would be quite excited to learn that there was a partnership between Fuse and Adobe Animate!
Is there a chance that the partnership is with Adobe Character Animator?
I can't quite say for certain of this Colin, all that I know, when I look at the programs that Mixamo is associated with and everything, it says that I can download, Adobe Fuse, Animate, Dreamweaver etc, etc, And when a person is looking for assistance in something, it says go to Adobe forum for help.
There are a lot of forums here, one for each Adobe product, and then sometimes sub topics too.
You should look at the Character Animator forum, I think there are more people there doing things like you want to do:
Colin, I have the information / answer that I needed, but thank you again for you assistance in this matter.
