Welcome to the challenge. Your plan sounds good.
Let's discuss it a bit, so you can get your story to Figurama app the best way possible. 1. Animations
Quill has a wonderful way to export animations using the Alembic format. This by itself is possible to get to run in Unity, by enabling the "hidden by default" package (explained in footnote 1) or using an older version of the package from GitHub. (https://github.com/unity3d-jp/AlembicForUnity)
The plugin assumes that the Alembic file is located inside Unity Project Assets folder, but in Figurama app, it is not present, and is only downloaded as an asset bundle from our servers. For this, Alembic is not yet operational in our app, but should be possible to fix & make the Alembic format work on Windows and Mac versions of our app (which are coming this month).
There is an issue, that this plugin doesn't yet support iOS/Android. This is still possible to fix, especially for Android, but for iOS is a bit more work. Doing so we are basically doing work for Unity and it's on our backlog, but it will not be possible this month yet. https://github.com/unity3d-jp/AlembicForUnity/issues/65
When we make Alembic work as part of our App for Windows and Mac versions and those become available to download, we can talk about bringing the fully animated scene to the app as part of your challenge submission!
2. Static scenes
Currently you can extract keyframes from your animated Quill scene and drop those into Unity as separate scenes, which will be connected via buttons (Load next scene). Subtitles are also coming in time for the challenge, in case you will want to add dialogue / captions / narration.
3. Camera movement
The camera movement is all in users "hands", so it will not be useful for the experience to create a pre-animated camera by yourself. The spawn point has indeed an attached camera, but is used only as a guide for you. The spawn point is used by the app only to position the viewer / player into the initial viewing position of the scene. After that the viewer / player will control his view by using touch/mouse/VR controller...
We are still working on the best possible controls for a story-experience, so that we are neither a 3D model viewer nor a 3D walkthrough. This part is handled by us
If you have any more questions or want to discuss something, feel free to respond. Good luck.
1.) The package is not discoverable in Package Manager of Unity. You'll need to manually add it to the [PROJECT NAME]/Packages/manifest.json file in your Unity project. You can do this by opening the file in a text editor (notepad, textedit, visual studio code,...) and adding the line below in the section called "dependencies".
"com.unity.formats.alembic" : "1.0.0-preview.7"
