I’m using 4.27 but can’t render out Object IDs as it freezes at the end of the rendering process. I can render EXRs fine but as soon as I add an Object ID pass to the render settings it doesn’t work and I have to force quit the app?!
If I render any other file type with Object IDs it works but this is not ideal as I need an EXR for all the mattes.
I’m rendering one frame if that helps?
