LIke Forian mentioned, I too was getting some exr’s named weird, in my case, it would stick in “.refraction.” into the render channel name, so that the assembler would never be able to find it.
I just tried the attached scripts on mine and all systems seem to work out. I did not modify the submitter at all and the previous file that I was struggling with seemed to come out fine (naming wise).
I’m going to try and modify the submission script now for our office and will keep you posted.
Thanks!
