SHAPES Brush features eight different brushes.
Each brush has three different functions, depending on whether no modifier key is used (Grab), SHIFT is held down (Smooth), or CTRL, which defines a different action depending on the brush:
Lets you to drag the mesh in screen space.
While holding down SHIFT the smoothing brush is activated. Smoothing is by default taking place as a relax function, which tries to keep the general volume of the mesh without shrinking effects.
If relax is turned off the smoothing will also shrink the mesh. The strength of the smoothing can be adjusted.
CTRL functions based on the different brush modes:
Allows you to move the mesh while keeping the underlying shape. Note, that the sliding is projection based, so if the brush size is set too large, geometry facing away from the camera (or in enclosed spaces) can be badly projected. This can result in stray vertices and is usually not desired. The general goal would be to set the brush size for sliding not too large and work in iterations.
Lets you pull the mesh out or in along the normals while dragging the mouse. The pull/push function is based on the mouse direction.
Lets you twist the mesh around the view axis while dragging the mouse.
Allows you to blend to a secondary mesh. First select the mesh you want to sculpt on, then shift select a second mesh you want to blend to. Choose the blend brush and while holding down CTRL you blend your mesh to the secondary selection.
Lets you brush your mesh back to it’s original state it was in when you began to start sculpting. The mesh is remembered as long as you don’t pick a different mesh and sculpt on that one.
Right-click the Erase button in the UI for additional options:
- Flood Erase erases all modifications since the sculpting started and returns the mesh to the initial state.
- Flush Cache erases any edits from the cache and bakes the current shape to the mesh. This can serve as a new initial state you can then erase back to.
Paint freeze areas to protect these parts of the mesh from any sculpting influence. Right-click the button to invert the frozen areas.
Erase Freeze Brush
Erases the previously frozen areas and makes them again respond to the action of the other sculpting brushes. Right-click the button to unfreeze the entire mesh.
