UsdMayaPrimWriter::Write should return bool indicating success or failure?

[jjzanin-SMS]

Hello,

We have many custom prim writers that inherit from UsdMayaPrimWriter and when there is an error during the Write function, we would like the export to fail. I propose that the UsdMayaPrimWriter::Write function returns a boolean indicating success or failure. When false is returned, the calling code returns and propagates the failure. The UsdMayaPrimWriter::PostExport could benefit from this as well.

Thank you for this suggestion. Sorry it took so long to respond. We'll discuss this internally.
