I'm using 3DS Max 2012 64 bit for Modelling. Since the last Update of the Game, i have a "Bug", that wasn't there before. It did appear like this: At the first Export, after the Game was updated, i still used the Exporter from before the Update, which worked properly before. But after the Update, i've got the below Message from some Files, that could be exported without any Problems before: I did make some Tests and it could be fixed by Remapping the Mesh. Then i thought it maybe has to do with new Shaders, that require to also use the new Exporter, that came with the latest Update. But with that new Exporter, 3DS Max just crashes in the Middle of the Exporting Process, without any Message. And it was the same Mesh that i had fixed and exported before, like written above. @Marcel Offermans and @Alex Sawczuk Is that a known Bug that will be fixed soon? Or can i get some Information, about a possible Reason for the Exporter crashing 3DS Max? BTW Would it be possible, to give the Exporter another Number for each new Version? That would give a much better Overview.
