Hi thekwen,
around your question, the issue occurs not only in .png,
you could check it directly into the Octane 3dsMax viewer, activating alpha channel in Type kernel and increase scattering value.
My advice is to save beauty layer and then use the alpha channel as a mask.
I will try to know more about the issue.
