Below is the finished HUB (both rendered and unrendered). This was fairly simple to put together, however, I did run into a few problems concerning the export to marmoset toolbag.
While exporting, I found that the bear’s model had some unnatural stretching. I found that this was due to enlarging the model within blender in order for the bear to tower over the others.
After much investigation, I figured out the model below is actually shrinking but not the armature itself, and the model is still attached to the armature. In order to fix this, I had to completely reset the size of the armature and the model, and then go through all the keyframes with the main model sized up.
