Project Explorer

The Project Explorer occupies the top of the right column. It is the tree-view answer to "what is in this project?" and switches between four perspectives via tabs.

Tabs

Tab	Shows	Use for
Objects	Scene graph of placements (Mesh3D / Image / Curve / Light / Camera)	Selection, hierarchy, hide / show, parent / unparent
Assets	Files referenced by the project, in groups: Textures, 3D Models, Brushes, Lights, Audio	Find an external asset; reveal in Finder; bundle into .esk
History	Action log: every undoable change in time order	Undo back to a specific point; bookmark a state
Sets	Named collections of placements	Bulk select, hide, render-mask

Objects tab

Each row shows an icon (mesh / image / curve / light / camera), the placement's id, and any markers (lock state, visibility eye, render mask). Click a row to select; Shift-click to extend selection; Ctrl-click to toggle.

Right-click a row for:

• Rename
• Duplicate
• Delete
• Parent under… / Unparent
• Convert to (Mesh3D ↔ Image, Curve → Mesh3D, etc.)
• Reveal in View Panel
• Open in Code (jump to paired Python handler)

Expand a row's triangle to see children (a Mesh3D's wing sub-transforms, an Image's landmark pairs, a Group's contents).

Assets tab

Lists external file references plus textures baked into the .esk. The top row, <projectname>.esk · Reveal in Finder, opens the bundle folder. Below it, files are grouped by kind:

Textures · 3
  textures/butterfly_albedo.png
  textures/butterfly_normal.png
  ../butterfly/iridescentwinged_butterfly.png   ↗ external
3D Models · 1
  _3ds/butterfly.3ds   ↗ external

External assets get a ↗ arrow. Click any row to highlight where it is used in the scene. Drag a row into the View Panel to drop a new placement instance.

History tab

A time-ordered list of every action: tool stroke, menu pick, value edit. Click a row to jump to that state (the rest of the undo history below is preserved but inactive).

Bookmark a state with the ★ button: useful when you have a working draft you want to come back to after experimenting.

Sets tab

A named collection of placement ids. The Designer creates one set automatically for landmark pairs (landmarks_butterfly); you can create more for your own selections via Edit > Group Selected… or right-click > Add Selection to Set.

Use sets to:

• Bulk hide all the model's helper geometry while you focus on a region.
• Apply a render-part mask to a set in one click.
• Animate every placement in a set in sync (the time slider's filter dropdown supports filtering by set).

Search

Press Cmd+F (macOS) or Ctrl+F (other) with the Project Explorer focused to fuzzy-search by placement id. Useful when a scene grows past 50 placements.
