Because of the design I chose, it was impossible for mixamo to move it, so I had to do the animation by myself with the rigify rig. And I don’t have enough experience to make the rest of the animations, so I’ll make another low poly character for the rest of the course. I’m quite happy with the result, though. I’m definetely going to use it in my portfolio. This is a great course and Grant is an amazing teacher.
And of course, thank you guys for the help! Much appreciated
