There are some incompatibilities between Closed and Open beta versions.
If you try to open an old .casc file (left) in the Open Beta Version (right), you’ll get a mesh with joints attached, but no controllers or other rig elements.
Note: If the scene includes animation, it too will be imported.
To migrate an old rig to the new version, you’ll need a file containing the prototype rig.
This file should be saved before the rig is finalized (before you click the Create Rig button on the Rigging Tool panel).
If you don’t have a file like this, try checking the autosave folder.
Autosave files can be accessed by selecting File → Open autosave file
This step should be taken during the rigging stage (before you click the Create Rig button).
1. Open the file containing the prototype rig.
2. Open the Rigging Tool panel
3. Click the Create JSON File button:
Note: this should be done before the rig is finalized. Otherwise, you won’t be able to migrate your rig: once the rig is complete, there is no way to generate a JSON file from it.
Migrating the Rig
1. Now, open the .casc file containing your character in the new version of Cascadeur.
You’ll get the mesh with the skeleton attached.
2. Select Import prototype rig... from the File → Import menu
3. Select the JSON file containing your rig.
4. Enable Rigging Tool
5. Set the Character mirror plane
For bipedal character, the YZ plane is usually a fitting choice
6. Click Create Rig
This way, you’ll get a fully rigged character.
You can also transfer animations from outdated scenes to the new ones.
To do this, you will need:
- An animated scene compatible with the old version
- A fully-rigged character compatible with the new version. This character should have the set of joints identical to the one you’ve used for animation.
1. Open the new scene
This scene should include the fully-rigged character(s)
2. Open the old scene in a new tab
This scene will include the mesh, the joints, and animation attached to the joints, but not any rig elements
3. Switch to Joint Mode
4. Select every joint (Ctrl+A)
5. Select the frames containing the animation you want to use
6. Select Copy Interval from the Edit menu (Ctrl + Shift + C)
7. Switch to the new scene
8. Once again, select every joint in the new scene
9. Select the same set of frames on the Timeline
10. Select Paste Interval from the Edit menu (Ctrl + Shift + V)
