Rhino Jordi Key Features

Modeling

The rhino model was created using Maya, starting with a base mesh and refined with quad-based topology for optimal deformation. I focused on maintaining clean edge flow and strategically placed edge loops to ensure smooth rigging and animation. The design was shaped to be cartoon-style, with exaggerated features, especially around the hump and legs. While I wanted to push these areas even further for more stylized shapes, it would have made rigging extremely difficult, so I kept the geometry functional for animation.

Rigging Process

I rigged the rhino using a custom auto-rigging system that I developed myself in Maya. The rig includes a self-created auto-clavicle system, with guidance from my professor Felix Gil. I also integrated ideas from Mothman, such as second skin and spread control for the fingers, which enhance the flexibility and realism of the rig. The rig features an FK/IK setup for the limbs and a flexible spine system. For added realism, I included a foot roll system, and the ability to adjust the shine of the eyes for detailed animation.

Since this was for my Master's thesis, I couldn’t afford to skimp on any details.

What I’ve Learned & Problems to Avoid

Throughout this project, I learned several valuable lessons. One key insight was the importance of modeling the quadruped in a neutral pose with the legs as straight as possible to avoid issues with mass deformation. Keeping the rig simple was another lesson I learned the hard way — I initially spent too much time creating a complex quadruped leg system, only to realize that the simplest, most stable solutions are often the best.

I also gained significant experience with Python while developing the auto-rig, which later helped me create a solid biped rigging tool. Having external guidance from professors and colleagues was crucial to overcoming challenges and improving my workflow.

Ultimately, the key to success was putting in a lot of effort, work, and passion into every part of the process.
