Sculpt

Sculpt moves the surface itself with a brush. Every stroke lands in a layer, so a sculpt survives a new face, can be dialled down, and can be switched off. It works on the GNM head and on a MetaHuman.

Sculpt: the tools on the shelf, grab picked; the layers and brush settings on the left.

Usage

  1. Open Sculpt. A layer is ready.
  2. Pick a tool on the shelf. grab is the default.
  3. Drag on the face. Drag the background to orbit. Ctrl inverts the brush; Shift relaxes.
  4. Use + layer to keep a change on its own. Lower a layer's weight to dial it down.
  5. Press done when you finish.

Tools

ToolWhat it does
grabDrags the whole area under the brush with the pointer.
pullPulls the surface out along its normal; Ctrl pushes in.
inflateMoves each point along its own normal, so a curved patch swells; Ctrl deflates.
bulgeStrengthens the relief that is already there; Ctrl flattens.
flattenPulls the area onto its own average plane; Ctrl bulges.
relaxMoves each point toward its neighbours, evening out the surface. Shift relaxes with any tool.
smoothTakes the active layer part of the way back toward the head without it, by the brush's strength. Other layers stay.
erasePaints the sculpt back toward the original shape.

On a MetaHuman

A MetaHuman has its own brush and its own layer stack. A converted character has a layer called GNM face: its weight dials from the MetaHuman's own face (0) to yours (1) and past it. With a body on, choose Head, Body or Both to say what the brush reaches.

A frame held on the Animation tab with Hold pose can be sculpted too: the strokes go to the rest shape.

TipThe Deformers tab can bake its result into a new sculpt layer, so you can erase it by hand.
