Hi Shelby,
Things are starting to clear up.
What I still don’t know, is how Assigning different Colors in Fusion is easier than assigning different Materials in Blender…
My guess is, that that comes down to the fact that you don’t know how to efficiently Select Vertices, Edges and Faces in Blender.
Like Grady and I have already mentioned above, you could (and probably should) simply use diferent Materials on 1 Object. Then you can always (make a backup copy and) Seperate By Material after that.
…
Personal opinion:
Importing something like this, instead of modeling it yourself, seems to be a lot more trouble than it’s worth. Apart from a messy Mesh (which should be cleaned up), look at what a horrible Outliner you get. If you want to have Separate Objects for Animation, then you should reallly rename all the different parts.
