Animating a character turnaround is a fundamental yet powerful exercise for developing body mechanics and expression in animation. In this hands-on tutorial, Animation Mentor instructor and industry veteran Jason Martinsen demonstrates his workflow for animating a 180-degree character turn using the Animation Mentor Darius rig in Maya. Whether you’re building your demo reel or strengthening your understanding of weight shifts, Jason’s process is practical, efficient, and full of clear tips. Watch the full video above.
Meet Jason Martinsen
Jason Martinsen has been a professional animator since 2006 and is currently a supervising animator at Sunrise Productions. He previously worked at Framestore, Reel FX, Sony Imageworks, and Blue Sky Studios on film productions like Storks and Ferdinand. Other projects include Scoob!, Back to the Outback, Rumble and Monkey King.

The Power of Reference
Jason opens the tutorial by underscoring the value of reference. He films himself turning around from several angles to study how real weight shifts, twists, and foot placement work. By observing and breaking down physical movement, you capture natural transitions—especially how the hips and shoulders compress, twist, and create asymmetry.
Setting Up for Animation
Jason uses the Darius rig in Maya, prepping the arm controls for maximum flexibility: one arm in FK for free motion, and the other in IK, constrained to a “sphere” prop for added challenge. The character interacts with the sphere, making the turn feel motivated rather than static. He aligns camera angles to match reference footage, then establishes key storytelling poses throughout the turn.
Blocking Key Poses
The turnaround is built on strong, readable poses:
- Initial pose matching the first frame of reference
- Head turn and initial weight shift
- Stepping across for the core of the turn
- Mid-turn pose as the body rotates
- Final planted pose facing the opposite direction
Jason emphasizes not to copy reference footage verbatim but instead, use it as a guide to exaggerate the most important moments. He focuses on shifting weight fully onto one leg before lifting the other, showing how a lifelike shift is essential to balance and believability.
Understanding Weight Shifts
The tutorial details several ways to move weight onto the supporting leg—by translating, leaning, or even sliding the foot. Jason explains how pivoting the foot under the center of mass allows the free leg to lift, discouraging common mistakes like animating steps without grounding the weight.
Adding Breakdown Poses
To smooth the transition and clarify mechanics, Jason adds breakdowns showing where the weight is centered, when the foot starts to twist and lift, and how the body leans into the new direction. He uses controls like foot roll and twist for nuanced pivoting, and demonstrates how even small toe twists add naturalism.
Iterating and Adjusting
As the shot is blocked out, Jason continues referencing both Maya and video to match movement, adjusting timing and arcs for maximum clarity. He works in stepped keys until satisfied with the structure, adding only as many poses as needed (about every five frames).
Splining and Refining
Once the blocking is solid, Jason switches to spline tangents for automatic interpolation. He uses Maya’s graph editor to smooth curves, add hang time, and adjust the motion for both the prop and the body. Cleaning up curves—especially for the center of mass—removes hitches and keeps movement fluid.
Polishing Details
Jason fine-tunes the motion:
- Adds subtle movements to toes and feet as they lift and plant
- Smooths knee pops using foot roll and translation
- Animates finger drag and arm overlap for believable follow-through
- Includes head turns, blinks, and eye darts for extra life and focus
He continually reviews from multiple camera angles, making small tweaks until the weight feels right and the action reads clearly.
Final Playblast
After the polish pass, Jason renders a playblast to check the animation as a whole. He encourages animators to view their work from all relevant angles and focus on timing, appeal, and clean weight shifts—the marks of a professional turnaround.
Key Takeaways
- Always begin with real reference for weight shifts and movement.
- Block strong key poses and use breakdowns for clarity and fluidity.
- Concentrate on transferring weight naturally before lifting limbs.
- Use stepped keys for blocking, then switch to spline and clean up in the graph editor.
- Refine details: foot pivots, arm overlap, facial cues, and finger movement.
- Review from multiple angles and polish until the motion feels natural.
