XRay Gizmos

0.2.10 — 2026-10-10

• The avatar budget panel also recounts after component and asset edits (e.g. My Avatar leaving its default menu out of the upload), not only hierarchy edits.

0.2.9 — 2026-10-08

• Avatar budget: the parameters bar shows the face tracking template’s share in light purple, as My Avatar’s face tracking settings do, apart from the avatar’s own and its custom base’s.
• Requires Orbiters Toolkit 0.3.18.

0.2.8 — 2026-10-06

• Avatar budget, a see-through panel over the Scene view: synced parameters as built, with VRCFury’s parameter compression when it applies, and the bones, PhysBones and contacts that set the PC performance rank, each with a custom base’s share. It replaces the budget cards of MCB and My Avatar.
• Avatar build copies leave out the Scene gizmos before avatar tools run: VRCFury sized every renderer’s bounds to include the armature gizmo.
• Requires Orbiters Toolkit 0.3.13.

0.2.7 — 2026-10-03

• Enable symmetry controls during Play Mode using Toolkit mirror overrides that survive the animation update.
• Keep editor posing changes separate from the uploaded avatar runtime.

XRay Gizmos is a Unity editor tool for showing armatures as xray overlay meshes in the Scene view.

Open it from:

Tools > Orbiters > XRay Gizmos

The window can display armatures for the active selection, a pinned object, or every skinned armature found in loaded scenes. Generated gizmo objects are hidden, editor-only, and not saved into the scene.

Clickable scene bones can be enabled from the window. When enabled, hovering an xray bone in the Scene view draws a white highlight, and clicking selects the matching bone transform in the hierarchy. Selected bones are also highlighted in white while the xray armature display is active.

Bone picking participates in Unity’s normal handle arbitration and yields to active drags, the View tool and camera navigation. Only the segment in front of the camera’s near plane is pickable. Shift-click adds a bone; Ctrl/Cmd-click toggles it. Hover is kept separately for each Scene view, and empty-space clicks remain available to Unity.

Mirror posing

Click Mirror in the Scene-view toolbar or the window. Mirror is a mode: it stays on while nothing can be mirrored and mirrors the rig of the avatar or bone you select next. Rotation and movement of one side are mirrored to its partner across the avatar root’s local X plane. The window shows the active rig and selected partner. It works independently of bone visibility and uses Toolkit’s shared editor posing service; XRay Gizmos supplies the rig when the selection is outside any humanoid.

Humanoid mappings and left/right bone names are supported. Mesh bind poses account for differing local bone axes; pairs without bind data use their enable-time pose, reported in the status. Undo includes both sides. Center bones and scale edits are not mirrored. Both-side selections preserve explicit edits on each side. Mirror pauses during animation preview and play mode, stays on through script reloads and binds again after bone hierarchy changes. Pairs under an unevenly scaled bone are skipped.

Clothing preview

With the VRChat avatar SDK in the project, Clothing (Scene-view toolbar and window) does what My Avatar’s Posing › Clothing does: clothing and accessories follow the pose of the selected avatar (or the scene’s only avatar) as they will once built, through VRCFury Armature Links, My Avatar attachments and matching bone names, and go back where they were when it is switched off. It lives in an optional assembly that compiles only with the SDK; without it nothing shows.

Requires Orbiters Toolkit 0.3.7 or newer within 0.3.x, declared in vpmDependencies. MCP for Unity is optional and is not needed for posing. When installing without VPM, install Toolkit alongside XRayGizmos.

Weight paint mode overlays Blender-style weight colors on selected skinned meshes for the selected bone transforms. Selecting only a bone searches loaded scenes for skinned meshes with positive weight on that bone. Selecting an Armature object or a renderer’s root bone displays the combined weight of all bones under that armature/root.

Mesh edge mode overlays polygon edges on selected skinned meshes. If only a bone or armature root is selected, it searches loaded scenes for skinned meshes using that bone or armature. The edge overlay uses optimized editor-only skinned edge meshes with configurable color and opacity.

ReFit debug labels are drawn automatically while ReFit debug mode is enabled. Each ReFit debug snapshot gets a readable Scene view label with a connector line to the snapshot, and nearby labels are separated to reduce overlap.

Avatar budget

With the VRChat avatar SDK in the project, the Avatar budget overlay (Scene view, bottom right; toggle it from the Overlays menu) shows where the selected avatar, or the scene’s only active avatar, stands against VRChat’s limits, estimated without building:

• Parameters: the bits of synced parameter memory the avatar uses once built, out of 256: its expression parameters and what VRCFury toggles, sliders and full controllers add. When the avatar goes over 256 and VRCFury’s parameter compression is on (its global setting), the bar shows the bits left after compression, how many parameters VRCFury compresses and how long a full sync of them takes. Only parameters a radial, toggle or puppet menu control drives can be compressed, as in VRCFury.
• Bones, PhysBones and Contacts: the counts that most often set an avatar’s PC performance rank, with the rank each reaches. Ticks mark the Excellent, Good, Medium and Poor limits from the VRChat SDK.

On a custom base (MCB), each bar shows the custom base’s share apart from the avatar’s, counted as built: PhysBones its build adds and bones it removes are included. The panel recounts shortly after the hierarchy or selection changes.

Notes

• The package has no dependency on MCB. The VRChat SDK is optional (Clothing preview only).
• Armature detection is based on usable SkinnedMeshRenderer bone arrays.
• Multiple meshes pointing to the same resolved armature are displayed once.
• Armature geometry is generated from the selected renderer’s bone array and follows the live bones through a SkinnedMeshRenderer.
• Scene bone picking uses the displayed xray armature segments and selects the matching source bone transform, not the hidden gizmo object.
• Weight paint uses a blue, cyan, green, yellow, red ramp over cloned editor-only skinned meshes, leaving source mesh assets untouched.
• Mesh edges are generated from source mesh vertices, active blendshape deformation, and bone weights, leaving source mesh assets untouched.
• Scene labels are editor-only GUI overlays; ReFit debug labels are detected from ReFit’s debug snapshot naming and editor preference without a package dependency.
