Re:Form paints on the vertices of the mesh itself — no UV unwrapping, no texture files, no separate program. Colour lives on the sculpt, deforms with it, saves with it, and rides along in GLB exports.

Getting started

Click the Paint tool (the droplet) on the left rail. The brush picker switches to the Paint group, and the Paint section appears in the right panel with the colour and material controls.

Paint strokes in the Lit shading mode. Paint needs resolution — subdivide before painting, since colour lives per-vertex.

Because colour is stored per-vertex, the mesh's density IS the paint resolution. Crisp edges need triangles — subdivide before a paint pass, and switch Shading to Lit or Unlit so colour shows true (see Lighting & display).

The Paint panel

The Paint panel: primary and secondary colour swatches, Wet Mix, Roughness and Metalness sliders, and the channel toggles
The Paint panel, shown while a paint brush is active.
  • Color — the primary colour the Paint brush lays down. Click the swatch for the picker.
  • Secondary — painted while Ctrl is held. Two colours, zero trips to the picker.
  • Wet Mix — how much of the colour already on the surface gets picked up and carried into the stroke. At 0 you lay pure brush colour; higher values smear through what you pass over, like painting wet-into-wet.
  • Roughness / Metalness — the material the stroke deposits alongside colour; see Roughness & metalness.
  • Color / Rough / Metal toggles — which channels a stroke writes. Turn Color off to paint material changes over existing colour, or vice versa.

Brush Size, Strength and Falloff work exactly as in sculpting — Strength acts as stroke opacity here.

The paint brushes

  • Paint — deposits the primary colour (secondary with Ctrl).
  • Blend — pulls the colours under the brush toward each other, easing them toward the mix at the brush centre. For softening the border where two colours meet.
  • Blur — a true blur: every vertex under the brush averages with its neighbours; repeated passes spread it wider. For melting fine colour detail evenly.
  • Smear — drags colour along the stroke, like pulling wet paint with a finger.
  • Fill — one click paints the entire mesh with the active colour and channels; Strength sets the fill opacity. Ctrl-click fills back to white. The fastest base coat in the business.

Practical notes

  • Paint strokes undo with Ctrl+Z exactly like sculpt strokes.
  • Symmetry mirrors paint strokes too — pupils land on both eyes at once.
  • Paint saves in your .clay project, and GLB export carries vertex colours into other tools. See Import & export.
  • Remeshing rebuilds the vertices, so paint after the topology is settled.
