Interface Overview
The main window has five regions.
- Title/Menu Bar - The top area containing the filename and main menu buttons
- Outliner/Scene Panel - Contains scene layers of mesh and textures, active texture channel type selection, right click menus and buttons to add or remove items.
- Preview Panel - Preview of textures/UV layout, controls for preview, some controls only become available after a pack.
- Control Panel - The panel with all input fields to control the packing parameters, including the 'pack' button
- Status Bar - The black horizontal status bar shows errors, packing progress in real time, along with the time and utilization percentage of a successful pack.
A general preview of the three main panels - outliner/scene, preview and control
The strip across the very top. It owns the standard window controls (minimise / maximise / close) plus inline buttons for project actions:
- New — start a fresh project.
-
Open — open a
.muvpproject file. - Recent files — popover listing the last ten projects you saved or opened up to 10 recent entries.
- Save — save the current project. Prompts for a path the first time.
- Save as — save under a new path or filename.
- Preferences — open the Preferences dialog.
- Help — open the about section with app version, and buttons to several important links, including this help wiki.

The left panel. Lists every mesh you have added to the project and, beneath each mesh, every texture bound to it. The outliner is where you build up the input set: add meshes, attach textures to them, assign channel types.
Full details: Outliner.
The top of the right panel. Shows either:
- A source texture (when you select a texture row) including the overlay of it's parent mesh layer's UV.
- A black placeholder representing the source mesh's UV space (when you select only a mesh row) or the wireframe/shaded shell layout of the selected mesh layer's UV.
- The packed atlas (after a pack, or when you flip the Atlas / Source toggle).
Full details: Preview.
The bottom of the right panel. All the knobs, buttons and input that affect the next pack: atlas resolution, padding, dilation, filter, packer choice, optional rotation, world-scale priority, output folder, atlas format, mesh format, and the Pack button itself.
Full details: Controls and Pack.
The strip across the very bottom.
- A thin progress line along the top edge fills during a pack and turns green on success.
- The middle reports the most recent pack result:
Pack complete in N s · utilization P%. This stays visible until you start another pack or open a new project.
By design the app does not have:
- A 3D viewport. The preview is always 2D — the source texture, the packed atlas, or a UV overlay drawn over either. (for now)
- A live re-pack. Changing a setting never triggers a pack. Packs only happen when you press Pack.
- A "Kind" picker per channel. Whether a texture is treated as a tangent-space normal map (and re-shaded under rotation) is inferred from its channel name. See Channel Types.
