Softimage provides a number of ways of recovering your work if your system crashes. In most cases, you can easily recover
your work by using the autosave and recovery mechanisms. You also have backup options that let you load previously saved versions
of your scene if you want to backtrack and rework some of your content.
Autosaving Scene Files
The autosave options in your Data Management preferences let you activate the autosave feature and determine how frequently
autosaves are made.
The autosaved scene file is created and maintained separately from the files you save while working. It is deleted when you
exit Softimage in a normal manner. You must still make sure to save your work each time you exit.
The autosaved scene file is maintained in the hidden System folder under the active project.
To set autosave
From the main menu, choose to open the Preferences window.
On the Files tab, activate the option.
By default, autosave is set to save every 30 minutes, but you can change this time span in the text box.
Backing Up Saved Scenes
Each time you save your scene, its file is automatically saved in a backup folder. This means you can go back and load an
earlier version of your scene if needed. This can also come in handy if your scene file could not be automatically recovered.
The default number of backed-up scenes is four, but you can change this number (to a maximum of 100) in your Data Management
To set backup preferences
Choose . Click and set the number of backups in the text box on the Files tab.
Set backups over a specified number of days with the option. This is useful if you save often and the last backed up version does not include the information you need. This option
ensures that you can retrieve your work from the last backed up versions of the n previous days.
TipMake sure you have enough disk space so that your backup files are created successfully.
To reload a scene file from its backup folder
Choose and navigate to your backup folder. By default, this folder is called Backup and is located in your project folder.
This folder contains all your saved scene files. These files are labeled , , etc., with being the most recently saved scene.
Select the required backup version and click OK to load the scene.
Recovering Scene Files
Recovering Scenes After a Crash
After a crash occurs, a dialog box usually opens indicating that your scene file has been successfully saved to an autosave
or crash backup directory in the project's System folder.
Softimage first tries to load the autosave file (if the Autosave option is enabled); if not, it falls back on the default
crashsave file. You can continue to use the scene after restarting Softimage.
To recover a scene file after a system crash
Restart Softimage after the crash. A dialog box opens asking if you want to try to recover the scene. Click .
If the scene is recoverable, an untitled scene opens with your latest work retrieved from the crashsave or autosave process.
Save the scene under a new name and restart Softimage.
Recovering a Scene with Corrupt Models
If a scene crashes when you try to open it, it may be that a single model is corrupt. You can try to recover the rest of the
scene using the recovery journal file.
To recover a scene that crashes on opening
Choose to open the Preferences window.
On the Scene Recovery tab, enter a file path and name in . For example:
Restart Softimage and open the scene.
As Softimage processes the scene, it writes to the file when it begins to load each model within the scene, and again after
it loads each model successfully. If Softimage crashes while loading a particular model, the journal file indicates that the
model never finished loading.
In addition when is defined, some corrupt clusters and cluster properties such as texture UVs are automatically fixed. When this occurs, the
cluster's full name is logged to the command history.
Restart Softimage and open the scene again.
Softimage reads the journal file, and skips the model that failed to load in the previous attempt.
You may need to repeat this step several times if there are several corrupt models in the same scene.
Once you have successfully recovered as much of the scene as possible, clear the contents of the Load Recovery Journal File
box to deactivate the option.
This speeds up the process of opening scenes because Softimage does not need to read and write to the file. In addition, it
allows Softimage to load models with the same name as those that were skipped, for example if you later open a backup of your
scene that was saved before the corruption occurred.
Recovering a Scene with Corrupt Operators
If you recovered a scene after crashing, it's possible that some operators are corrupted and are causing instability. You
can try to hunt down and remove the operators that are causing problems.
To diagnose and fix operator corruption
On the Scene Recovery tab of your Data Management preferences, activate .
Open the problematic scene. Note that all operators in the geometry, texture, and envelope stacks have been disabled.
Try to find the corrupt operator. For example, delete the last operator you added, and then re-enable the stack from the bottom
to see if the problem goes away.
For information about enabling operators in the stack, see Disabling the Top of the Stack [Modeling and Deformation Basics].
Once you have found the problem and deleted that operator, save the scene and press Ctrl+N to start a new scene.
Deactivate . Do not keep working with this option on — it is a debugging tool only.
Re-open the scene. The operators are now active and you can continue working.
Recovering a Scene with Corrupt Polygon Meshes or Clusters
If you are having problems with a scene, it's possible that some polygon meshes or clusters are corrupt. You can find these
meshes and clusters and try to recover your work.
To diagnose and fix polygon mesh corruption
On the Scene Recovery tab of your Data Management preferences, make sure that is on.
Open the problematic scene.
If cluster corruption is found, it is fixed automatically and the names of the clusters are logged to the command history.
You should check these clusters to make sure that they still contain the same components and properties (texture UVs, vertex
colors, weight maps, and so on) that you expect. There might be additional cluster corruption that you can find and fix by
freezing all or part of the operator stack, because corruption is not detected in unfrozen data.
If mesh corruption is found, the name of the object and the indices of the illegal components are logged in the command history
and you are prompted to hide the mesh (to avoid potential crashes when drawing the corrupt mesh structure).
To fix mesh corruption, first try to unhide the object and select all its polygons.
If you can't unhide and select the polygons without crashing, try selecting all the polygons by typing the following into
the name selection box in the Select panel:
Choose from the Model toolbar.
A new mesh object is created from the polygons of the corrupted mesh.
Freeze the new mesh object.
If no new messages about corrupt components are logged, you have successfully fixed the corruption. Delete the original mesh.
Otherwise, continue with the next step.
Try to recover part of your work by selecting the uncorrupted polygons (leaving out an area around the corrupt components)
and then repeating steps 4 and 5. Unfortunately, some corrupt meshes cannot be recovered.
