Howdy, I have a model which is throwing intermittent errors upon the scene being read. The error says:
// ERROR : 2000 - Mesh structure error (corruption) was detected on mesh _______ while loading it. See below for precise information about corrupted components. // ERROR : 2000 - List of corrupted vertices: 276, 278, 4535, 11632, 14802, 14865, 14880, 14892, 14898, 14944 // ERROR : 2000 - List of corrupted edges: 523, 36828, 40348, 40447, 40529 So what's weird about this? The mesh is about 60K polys and about five edges and ten vertices(all associated to the 5 edges) are being reported as corrupted. There are nearly 70 copies of the SAME model in the scene. Generally only one or two throw the error during a scene read and I have seen about 6 or 7 different ones throw the error during the lifetime of this project. The geometry was originally created by me in Maya as NURBS and exported to Soft. There is no external geometry not created by me. I have the offending geometry isolated as a model, I can read it(import) into a clean scene with no problems or errors. However, upon importing it, during interrogation of the offending geometry I find that: 1. It is a single mesh, though there are islands within the mesh. 2. There are no non-manifold edges or vertices associated to the offending components. 3. There are no duplicate edges or vertices associated or near the offending components. 4. There is nothing unusual about the listed edges or vertices, they all look clean, adjoined, and normal. 5. A couple of the edges are border edges, but they also appear clean. 6. Selecting and modifying these vertices and edges have caused several crashes. 7. These crashes during interrogation are occurring on a model that was created in Soft immediately after Maya export. As a result, the errors appear to have nothing to do with the master scene that this model was imported into afterwards. Generally I've been ignoring the errors for the duration of the project, until recently. If the scene loads everything it seems to hold up just fine regardless that it generates the error warnings, but I'm starting to run into issues where the scene crashes upon loading once it spits out the error on the geometry. Subsequent reads sometimes succeed and some fail. I'm getting concerned that with time the scene may eventually fail upon read indefinitely. I'd really rather not drag this back to Maya for a cleanup if I can avoid it, I've applied clusters and local materials to the mesh from within Soft. If anyone has any suggestions for a "cleanup" procedure, I'd love to hear them.
