Studio and Graph › The Viewport

Overlays and Readouts

The pane badge, frame rate, mesh statistics, camera lock, axis gizmo, light widget and the rest of the chrome drawn over the view.

Both panes draw the same set of overlays on top of the 3D view. Some are always on; others only appear in specific conditions.

Overlay	Text shown	When it appears
Pane badge	SOURCE / TARGET	Always, top-left of each pane.
FPS pill	the frame rate, FPS, the frame time, ms, and a colour dot	Always, top-left, just below the pane badge. The dot and digits are green at 60 FPS or higher, amber from 30 to 60, and red below 30.
Sculpt-data pill	"Preparing sculpt data..."	Top-centre, while this pane's mesh has GPU sculpt buffers requested but not yet ready.
Turntable pill	"Turntable: {status}" plus a Cancel button	Top-centre, while a turntable render is running for this pane. Cancel's tooltip is "Stop after the current frame. Frames already written are kept and the camera is restored."
Camera lock button	icon only, no text	Always visible; see Camera lock below.
Reference-mesh eye	icon only, no text	Source pane only, and only when this pane actually has a reference mesh loaded; see Reference-mesh eye below.
Axis gizmo	the letters X, Y, Z	Always, bottom-left, just above the camera read-out pill.
Light widget	a vertical slider plus a rotation globe	Always, bottom-right; see Light widget below.
Accept / Cancel banner	Accept and Cancel buttons	Bottom-centre, only while a tool is active - the same row the navigation hint strip otherwise occupies.

Camera lock

The icon tints to the theme's accent colour when locked on, and dims to grey when off. It starts off and persists across sessions.

State	Tooltip
ON	"Camera lock ON - Source / Target cameras move together. Click to unlock."
OFF	"Camera lock OFF - Source / Target cameras move independently. Click to lock."

Reference-mesh eye

This button only appears on the Source pane, and only once the Scene outliner has a Reference Mesh row pointing at something for this pane - otherwise it is not drawn at all. Clicking it does the same thing as toggling visibility on that Scene row.

State	Tooltip
Hidden	"Reference mesh hidden - click to show."
Visible	"Reference mesh visible - click to hide."

Axis gizmo

Three short lines radiating from a centre dot, labelled X, Y and Z, about 28 px across. The axes are drawn back-to-front, so whichever ones face the camera are brighter. Colours are themeable (see Orientation gizmo on the Theme page); the shipped defaults are red for X, green for Y and blue for Z.

Mesh Stats

The Mesh Stats pill's label never changes. Opening it rebuilds a small read-out panel from whichever mesh belongs to this pane - the Source pane's primary mesh, or the Target pane's secondary mesh.

Row	Meaning
Mesh Statistics	Panel title, centred.
Vertex Count:	Vertex count.
Triangle Count:	Triangle count.
Edge Count:	Edge count.
UV Channels:	Number of UV layers; 0 if the mesh has no attributes.
Bone Count:	Number of bones; 0 if the mesh has no bones.

Two empty states replace the whole dropdown with a single line of text instead:

"No mesh available" - there is no mesh component for this pane at all.
"Mesh is empty" - a mesh component exists but has zero vertices.

A translucent pill at the bottom-right holds two controls, both always visible:

Intensity slider - vertical, range 0 to 5, default 1.0. Tooltip: "Directional key light intensity. Drag to brighten / dim the main light (Persona default 1.0). The SkyLight provides constant ambient fill."
Rotation globe - about 40 px across. Tooltip: "Drag to rotate the sun. Mouse-wheel adjusts pitch. Double-click to reset." It paints the cardinal letters F, B, R and L on its face, and prints the current yaw and pitch as whole-degree numbers labelled Y: and P:. Default rotation is pitch -50, yaw -75.

Appears bottom-centre only while a tool is active.

Button	Tooltip
Accept	"Apply the active tool's pending changes and propagate the result to the node's output pin(s)."
Cancel	"Discard the active tool's pending changes and exit the tool without writing to the node's output pin(s)."
