drag to paint the protected region · dims in the viewport
Paint a region on the form, then press Lift it. It becomes an object of its own that keeps following this form until you Bake it.
Two ways: Draw axis bends about a line; Find bones finds joints, and a ball gets one.
no bones yet
Press Find bones, then drag a joint to bend the form around it.
no axis yet
Draw a line across the form, then drag to turn around it.
Drag an arrow to move, a ring to turn, a cube to scale. Elsewhere orbits.

Other methods
Three older routes, kept for the cases that want them. Each runs on press.
Drag on the model to add a limb as thick as the brush.
Draw a closed loop to inflate it. A loop inside cuts a hole.
Loop what to make level; cross the form's edge to slice that part off.

Pgon needs WebGL2

This browser or device didn't offer a WebGL2 context. Pgon does not need WebGPU, and WebGL2 has shipped in every current browser for years — Safari added it in 2021, the others well before that. Seeing this screen usually means WebGL2 has been switched off, not that the hardware can't run it.

Touch & Pencil

Pencil — sculpts anywhere, even over empty space
One finger — sculpts on the model, orbits the view off it
Two fingers — pinch to zoom, drag to pan
Two-finger tap — undo
Three-finger tap — redo
Press and hold any control — opens its card
Double-tap an object (Place, Gantry) — work on that one
A finger is ignored while the Pencil is drawing.

Keyboard (desktop)

Cmd+Z / ⇧Cmd+Z — undo / redo
Shift+drag — smooth, any brush
Ctrl+drag — paint mask, any brush
Ctrl+click empty space — invert the mask; Ctrl+drag a box there — clear it
Alt+drag — invert (Build/Inflate/Crease/Pinch/Swirl)
X — cycle symmetry (X, Y, Z, the pairs, all three, Radial, off)
F — frame camera

Your files

Every sculpt gets a name — two words, shown in the Project panel.
Everything you export or save from it carries that name, so your work stays together.
The number counts up with each export, so the highest one is the newest.
Save project keeps everything — levels, mask, settings — and reopens exactly.
Export writes the shape only, for another program.
Reopening a saved project keeps its name and carries on counting.

Growing the form

In Grow, press Grow a blob and drag on the model — brush size sets how thick.
A tap makes a ball; a drag makes a limb.
Melt sets how much it swells into the form at the join.
Do this early: it rebuilds the surface, which clears your subdivision levels.
Block the form out with blobs first, then divide and sculpt.

Surface patterns

Size — how big the features come out on the form.
Amount — how deep the pattern cuts.
Curve — what the pattern's values become: islands, mesas, terraces.
Protect — lays the pattern down as a mask instead of as shape.
Press and hold any of them for the full explanation.

SurfStruct
Stroke

Alpha

A stamp that shapes what the brush deposits. White pushes, black doesn't.

Stroke

How the brush follows your hand, rather than what it does when it lands.
Text
Sets a word into the surface where you are looking. Orbit to aim.
Deform
Shapes the whole form at once. Mask a part to hold it still.
Axis
Pattern
A field in space, not a stamp — it wraps the form with no seam.
Lumps and grain
One fractal field, three remaps and one drawing of it.
Cellular
Regions that know their neighbors, one point per cell.
Woven and molded
These have a direction, and wrap rather than smear.
Made of rules
A rule, stated exactly, made into a surface.
Grown
These are RUN, not looked up — they compute once, then behave like any other.
Curve
Lattice
Watch a setting travel; stop it where you like.
What travels
Travel grows a setting up to yours; Hold keeps it; Random picks one.
Terrain
Paint a patch, choose a place, press Apply. Unpainted, it wraps the form.
Protrusions
Shoots over the whole surface — moss, thorns, villi — as their own object.
Cage
Struts as a new object.
Infill
A lattice and skin in one melted body; the form is hidden, not deleted.
