Concepts

Project

A project is simply a folder on your computer holding all the assets needed for your application. When you start a new project, a default folder structure will be created.

Application

Your application is the entry point of your project. It is represented by a single .uia file at the root of your project folder. This file references the presentation and sub-presentations in your project. The application is what is displayed by the Viewer.

Presentation

Artists use Studio to create presentation files, represented by .uip files in your project. A presentation has one or more layers composited to the screen, comprised of 2D and 3D assets created in other applications.

Each application can only have one main presentation shown on screen (specified by the .uia file) but this presentation may reference other sub-presentations, either on flat layers or as images and textures drawn in a scene.

QML

Additional functionality can be built on top of the Qt 3D Studio presentations with QML by incorporating applications or presentations into QML with the Studio3D element.

Layer

A single Studio presentation combines one or more layers. The visual result of each layer comes from rendering a 3D scene, 2D scene (via an orthographic camera), or sub-presentation. Layers are then composited with items on upper layers drawing on top of the content on lower layers.

Slide

A Studio presentation combines 3D assets with animations and slides. Slides can be thought of as states and provide visual variations within the presentation.

Known Issues

Possible problems after automatic mesh optimization

When loading a presentation made with an earlier version (2.0 beta2 or older) of Qt 3D Studio which has imported FBX or DAE models, you may see the following messagebox:

{Old presentation version}

If your imported models are not visible in the Viewer after seeing the message, you need to edit your *.uip file(s) manually. Some older versions of Studio referenced meshes with revision number in the *.uip file, and that revision causes it to be missing in the scope of the Viewer.

You'll need to find all occurrences of .mesh#<revision_number> from you *.uip and replace them with .mesh.
