Problems and Resolutions Assertion Failed Errors The assertion failed error occurs commonly when you try to load a corrupt file. The error gives you a line number and file name where the corruption occurred. You are then left with the options to retry or cancel. Unfortunately, the line number and file often don't help because that isn't necessarily where the error is actually occurring. Most people click the Retry option a couple of times then give up, fearing they've lost many hours of work. Don't panic yet. There are a number of things you can try before you have to start rebuilding. The first thing to try is keep clicking the Retry button. If there is a corruption to the vertices of an object, you might have to parse through each vertex until you bypass the object completely. For example, Autodesk Product Support once received a file that returned an Assertion Failed error referencing a tab.h file. The scene recently had an AutoCAD component imported that 3ds Max couldn't understand. However, after the support technician clicked the Retry button 88 times, the scene finally opened. After resaving the scene, it opened without incident. Merging Corrupt Files If normal attempts to open a scene fail, another thing you can try is merging the scene. If the file is not too corrupted, you would be able to access the Merge dialog which shows a list of the components in the scene. This is a good sign because, with a little effort, you can fix the file yourself. You now need to narrow down which object, or objects, are causing the load failure. 1 Start 3ds Max. 2 Choose File menu > Merge. 3 Browse to the folder containing the model, select the model and click the Open button. The Merge dialog is displayed, showing all the components in the scene. 7860 | Chapter 28 Troubleshooting 3ds Max
