Since a few days Mayabatch stopped working. I've used it without problems untill last Monday, but now when I try to start a batch render it immediately returns "Rendering Completed. See mayaRenderLog.txt for information" after it has started. Maya does this for every engine I try to render with (Software, Hardware 2.0, MentalRay, VRay).
This is what my render log looks like:
Starting "C:\Program Files\Autodesk\Maya2012\bin\mayabatch.exe"
Qt: Untested Windows version 6.2 detected!
// Maya exited with status -1073741819
The QT warning is because I'm on Windows8Pro, but it has worked flawlessly till last Monday. Any clue?
