Ghosting

Brush over triangles to mark them, then click the eye to make them disappear. Hidden geometry is only hidden: nothing is deleted and nothing is painted, so unhiding returns your artwork untouched. A set you use often can be saved as a named ghost and recalled later, and named ghosts are stored with the project.

Marking and hiding are two steps. Marked triangles get a translucent cyan tint, and they vanish when you press the eye.

Option bar

• Eye - Hides or shows the marked faces. Comes alive once something is marked.
• Ghost - Brush: mark the faces you brush over. Hold Shift to un-mark.
• Lasso - Add everything inside the loop, front and back, at any depth. Hold Shift to remove.
• Cx - Select Connected: click a part and everything connected to it joins the ghost. Hold Shift to remove.
• Flip - Flips the selection: marks everything that is not marked.
• -Cx - Select Connected in reverse: click a part and everything connected to it leaves the ghost. Hold Shift to add.
• -Lasso - Removes everything inside the loop, at any depth. Hold Shift to add.
• -Ghost - Brush: un-mark the faces you brush over.
• ... - Opens the Ghost Paintings window, for saving and restoring named ghosts.
• X - Exit Ghost: clears the selection, shows everything and hands you the Brush.

The six mode buttons look like two pills but are one set: only one is ever active, and Ghost is the default.

Ghost Paintings

A name field with Save, Restore and Delete, and ten default slots named Ghost 1 through Ghost 10. Restoring replaces the current marked selection and hides it, so only one ghost is active at a time. Delete asks first. Escape closes the window.

Mouse, stylus and modifiers

• Shift - Inverts add and remove in every mode, brush, lasso and connected alike.
• Double-click in a brush mode - Selects or deselects the whole connected piece, without starting a stroke.
• Cx modes - Need a click, not a drag, so orbiting never fires them.
• Cursor color - Cyan when adding, lime green when removing, including a Shift-inverted removal.
• Undo and Redo - While the Ghost tool is active these move through the ghost marking history rather than the paint history. Hiding, showing and saving stay put through an undo.

Notes

• The brush marks a world-space sphere at the raycast hit, sized by the brush Size, limited to the front shell so it stays on the side you can see.
• Ghosting persists when you switch tools, and the dock icon turns cyan whenever anything is hidden, as a reminder that part of the model is missing on purpose.
• Entering the tool clears any active reference-image overlay.
• One drag is one undo group.
