Mesh Generation

Turn a sprite's alpha into a deformable cutout mesh you can weight-paint. The panel is mesh-only - on a sprite element it warns and points you at bone-parenting (Ctrl+P > Bone) instead. It shows the target rig (picked in the Skeleton panel) and hosts the trace parameters both entry points share: the Interior Mode selector (Simple = sparse, Dense = filled), Contour vertices (the outline budget), and Interior spacing (the fill spacing, also the free-draw resample and fold-snap radius in the interactive modal). The dense-only fields - Density follows bones and its bone radius / factor - grey out under Simple mode.

Automesh from Alpha​

A one-shot trace that walks the image alpha contour into a mesh; re-runs preserve the UV-pinned base quad. Its own settings (the rest live on the parent panel above):

  • Trace resolution - an image downscale factor. A higher value (1.0 = full image) traces a finer silhouette but costs more; it sets outline fidelity, not the vertex count.
  • Alpha threshold and Margin pixels - the alpha cutoff for the contour and how far to inset or outset it.
  • Preserve base quad - keep the UV-pinned base quad across re-runs.
  • Preserve weights on regen - snapshot weights by UV before the regen and reproject them onto the new mesh; off, the regen wipes paint. Surfaced here because this button triggers the regen (the same toggle lives in the Weight Paint Snapshot subpanel).

Automesh Interactive​

A modal preview of the same trace. Advance through the stages to cut / extend the outline and place interior points, then commit; nothing is written until you confirm the final stage. Its inputs are the inner-loop count and spacing, the cut margin, and the same Preserve weights on regen toggle. The button greys out until the active object is a mesh with an image texture.

Debug Pipeline​

A developer aid, shown only with debug mode on (Preferences > Add-ons > Proscenio). Pick a stage of the trace and the next run leaves a wireframe companion in the Proscenio.Debug collection; Clear Debug Companions removes them.
