Interface Overview

The main window has four regions. Their relative sizes can be dragged.

Title bar

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 .muvp project file.
• Recent files — popover listing the last ten projects you saved or opened.
• Save — save the current project. Prompts for a path the first time.
• Save as — save under a new path.
• Preferences — open the Preferences dialog.
• Help — open this wiki.

Full details: Title Bar and Project Files.

Outliner

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.

Preview

The top of the right panel. Shows either:

• A source texture (when you select a texture row).
• A black placeholder representing the source mesh's UV space (when you select only a mesh row).
• The packed atlas (after a bake, or when you flip the Atlas / Source toggle).

A SVG overlay can draw the UV wireframe and / or the filled UV shells on top of whichever image is showing.

Full details: Preview.

Controls and Pack

The bottom of the right panel. All the knobs that affect the next bake: 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.

Status bar

The strip across the very bottom.

• A thin progress line along the top edge fills during a bake 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.
• The right side has a Help button.

Resizing the panels

Drag the vertical gutter between the outliner and the right panel to give one or the other more room. Drag the horizontal gutter inside the right panel to balance preview vs controls. Splitter sizes are saved into the project file (.muvp) so they persist per project.

What is not in the interface

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.
• A live re-pack. Changing a setting never triggers a bake. Bakes 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.
