The polar bear proved to be the most difficult to both rig, weight and animate due to all of its individual parts. Due to it having multiple parts and a moving mouth, the model required more bones than usual.
As you can see below, the model needed bones for the fingers, eyebrows and the mouth in addition to everything else.
The weight painting needed to be manually applied to the teeth and gums, which due to blenders’ poor transparency mode within weight paint mode proved incredibly tedious.
Below is one of the poses within the animation and from here it works quite well, apart from the arm bones distorting the main body, which couldn’t be helped.
I had to add it a few animations so that the characters could somewhat interact with each other within the main HUB, however, this wasn’t too much trouble.
