VTuber Reference Sheets: What Riggers Actually Need From You
What a rigger actually needs beyond a single nice illustration — and why it's easy to miss on a first pass.
A gorgeous single portrait is often the first thing a new VTuber commissions — and it's frequently not enough for a rigger to actually work from. Rigging needs to understand how the character's parts move relative to each other, which a single static pose doesn't show.
A clean, forward-facing neutral pose
Rigging is built around a neutral base — arms in a natural resting position, face forward, minimal foreshortening. A dynamic action pose might look better on its own, but it's the wrong reference to rig from.
A real expression range, not just the one
Facial rigging (blend shapes, Live2D deformers) needs to see how the face actually changes between expressions — eyebrows, eye shape, mouth — not just one polished smile. A neutral, smile, angry, and surprised set covers the range most riggers ask for as a starting point.
Side and back views for anything that moves
Hair, ears, tails, loose clothing, accessories — anything that's going to sway or bounce in the final rig needs to be understood from more than the front. A side view shows how far something extends; a back view catches details a front-only reference misses entirely.
None of this replaces the rigger's actual work, but showing up with a full reference set instead of one portrait is the difference between a rigger asking follow-up questions for a week and getting straight to rigging.
