The Handoff

Stage-to-stage checklists for a VTuber model build. Copy one, send it, tick it off offline — or run it inside a room where each tick records who and when.

The Handoff is the gate between illustration, cutting, rigging, and shading. These checklists name what should be agreed before the next stage starts. Yubikiri does not open your PSD or validate layers — in a room, each item is a dated attestation: who ticked it, and when both sides can see.

Illustration → Cutting

Cutting → Rigging

Cut parts exported and named for Live2D (psd, png)
Layer / part naming map shared (txt, pdf)
Mesh / deformation notes for rigger
Expression parts ready for binding (psd, png)
Cut stage approved by client before rigging starts

Rigging → Shading

Model export ready for lookdev (json, moc3, model3.json)
Texture set / atlas delivered (png)

Rig stage approved by client before shading starts

Illustration → Rigging

Direct handoff when there is no separate cutting stage.

PSD/clip layers separated and named for rigging (psd, clip)
Cut requirements documented (hair, clothes, accessories)

Inside a linked room

The same items appear between linked commission rooms in a build chain. When someone ticks an item, the room records their name and the date — a shared record instead of a screenshot thread. Linked rooms today share one payee on milestones; collaborators join for files and handoffs, not separate Checkout per vendor.
