SelectionSphere

Inherits from: PVAdornment → GuiBase3d → GuiBase → Instance → Object

SelectionSphere renders a 3D sphere around its Adornee when it is a descendant of the Workspace or anywhere where GUI objects are rendered. The sphere's geometry consists of a ring/outline in addition to a surface. SelectionSphere does not capture any form of input; it is solely a visual effect.

For an outline/fill overlay effect which covers non‑primitive geometry such as that of a MeshPart, see Highlight.
