Hi there, thanks for this awesome 1.6 version, really nice upgrade, good to see this piece of bytes going such a good way ! 
I facing an issue to get a good alpha channel after saving from the Corona IE..
Saving in exr/png doesnt give me any alpha channel, or a full white one. I’m used to work this way and understand how it works, but here…
I’m working with and HDR in environment slot & with lightmix.
How to get it ?
Thanks I feel dumb ! 
it is a bug, scheduled to be fixed in hotfix1
Ok good to know !
Also, when getting alpha through TIFF files from VFB, I always get this kind of white edges… see attchd
I paste the alpha, or get it from CTRL+clic on a layer into PS to get it from the channel, but I always keep this stroke… is it a bug too ?
Thanks ! 
No, u should render with black background and then put the
Background in Photoshop. An other way no so clean is to
Use defringe in Photoshop
Well done for defringe command, I forgot it as dont have this issues on Vray usually…
I never rendered with a black BG in other render (Vray, Maxwell…) and never got fringes using my method… weird to got them in here…
