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
1. Choose File > Preferences to open the Preferences window.
2. Click Data Management.
3. On the Scene Recovery tab, enter a file path and name in Load Recovery Journal File. For example:
C:\Temp\xsirecovery.txt
4. Restart XSI and open the scene.
As XSI 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 XSI crashes while loading a particular model, the journal file indicates that the model never finished loading.
In addition when Load Recovery Journal File 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.
5. Restart XSI and open the scene again.
XSI 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.
6. 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 XSI does not need to read and write to the file. In addition, it allows XSI to load models with the same name as those that were skipped, such as 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
1. On the Scene Recovery tab of your Data Management preferences, activate Disable all geometry operators on load.
2. Open the problematic scene. Note that all operators in the geometry, texture, and envelope stacks have been disabled.
3. 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 in Chapter 3 of the Modeling and Deformation Basics guide.
4. Once you have found the problem and deleted that operator, save the scene and press Ctrl+n to start a new scene.
5. Deactivate Disable all geometry operators on load. Do not keep working with this option on — it is a debugging tool only.
6. 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
1. On the Scene Recovery tab of your Data Management preferences, make sure that Detect corrupted polygon meshes and clusters upon load/freeze is on.
2. 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).
3. 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:
objectname.poly
4. Choose Create > Poly. Mesh > Extract Polygons (keep) from the Model toolbar.
A new mesh object is created from the polygons of the corrupted mesh.
5. 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.
6. 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.
