Show/Hide Warning Manager


This option lets you disable the Warnings and Errors dialog box that appears during the export process. The Warning manager is active by default.

What is the Difference Between an Error and a Warning?

The 3ds Max FBX Plug-in uses errors and warnings to alert you of conversions and potential problems during the export process.

When something unexpected occurs during the conversion, the plug-in reports an error. An error occurs when the plug-in encounters an unknown behavior and the conversion is going to produce an unexpected result.

When the plug-in must apply a conversion to the source data for it to be in a format that the destination application can read, the plug-in reports a warning. This warning is not the indication of a problem, but is there to provide a report of conversions that the plug-in has applied to the outgoing data.
