Good day everyone, One quick question, is this merge creating a multipart exr? Recently, we've been talking in my studio to move from single channel exrs to multichannel, the only reason why we haven't is due that Arnold doesn't render multichannel multipart exr. We have been thinking to do it on a post-render process however, if oiio tool would merge single channel to multichannel multipart exrs we could keep the same workflow and merge on a post render process.
