Practical tip

Think “paint where supports are allowed.” Purple adds support. Red forbids support. Grey removes your paint so the slicer decides again.

Fuzzy Skin painting tool (Fill, Smart Fill Angle, Section View)
Smart Fill Angle

Limits what the Fill tool considers “connected” based on surface angle. Smaller angles stay on similar faces; larger angles spill around corners.

Section View

Lets you cut the view to paint interior or hidden surfaces without rotating endlessly.

Brush vs Fill
  • Brush: you paint exactly where the effect applies.
  • Fill: flood-fills connected surfaces (controlled by Smart Fill Angle).
