  • Render Elements inconsistently failing to output when rendering animation

    Hi all,

    I'm having an issue where I'm rendering an animation with GPU on a single machine (using V-Ray for Modo as the host app). Some frames output EXR files that can't be opened. More than that, sometimes the beauty pass EXR renders and saves correctly, but the associated diffuse or depth pass EXRs for that same frame don't save out correctly and can't be opened.

    This is happening quite frequently over a 200 frame animation.

    Re-rendering the frames fixes it, so it seems to be highly inconsistent and I can't see anything within the output log that suggests anything went wrong in the rendering process.

    The log for one of the frames pictured below specifies... ! (logsys) Successfully written image file "E:\Aquilion Exceed LB\Renders\Frames\SFA_Accurate\Test.0195.exr"

    If I have to go through every frame of every render element to do manual cleanup and re-render, this is going to be a huge pain!

    Thanks for any advice on what might be happening and what could be done to remedy it.
