The Build group is where mass comes from — brushes that raise, press, cut and gather the surface. Hold Ctrl with any of them to invert: builders carve, cutters raise.

Draw & Draw Sharp

Draw raises the surface outward along its own normal — the general-purpose "add material here" brush, soft and round by default.

Draw Sharp draws a crisp, sharp-crested ridge instead. Where Draw makes a dune, Draw Sharp makes a mountain ridge — inverted, it cuts a sharp-bottomed groove, which is the go-to for wrinkles and cut lines.

Carve

Carve is Draw Sharp's inverse by trade: it slices a sharp gouge into the surface. Repeated strokes deepen the same cut rather than stacking noisily. Hold Ctrl to raise a thin seam instead.

Clay & Clay Ribbon

Clay builds material toward a plane hovering over the surface — like pressing strips of soft clay on with your thumb. It's the workhorse for blocking form because it fills and levels as it builds.

Clay Ribbon is Clay with a squared, ribbed build-up — strokes lay down like flat ribbons of clay. It's fast, constructive, and leaves a surface that reads as sculpted, which many people prefer to keep.

Inflate & Crease

Inflate pushes vertices out along their own normals — forms fatten evenly in every direction, ideal for filling out limbs, cheeks and pillowy shapes. Inverted, it deflates.

Crease cuts a sharp valley and pinches the sides together as it goes — the definitive brush for fold lines, seams between forms, and anywhere two masses meet.

Fissure 01 & Fissure 02

The fissure pair cuts crack lines. Fissure 01 slices a smooth, clean V-cut — strokes blend into one continuous cut, and a new stroke slices into the last, so cracks join up the way real ones do. Fissure 02 is its wilder sibling: a wandering, hand-drawn crack with kinks, for stylised stone and wood wear. The Jitter slider sets how wildly it wanders. Both raise a thin seam when inverted.

Pinch

Pinch pulls vertices toward the brush centre, tightening whatever is under it. Its classic use is sharpening: run Crease to cut a fold, then Pinch along the same line to draw it tight.
