Yeah I tried unpremultiplied, still not much better.

 

I think I will be using the unlit transparent mode, it clips the puffy black stuff.

Have you turned off alpha premult in your render options?  I always have to do this with all my particle passes to get them to comp right.

Anyone get odd Alpha's using Binary Iris?  I begand doing some tests, and came across this problem...

Look at the attached image and you'll see what I mean.  The RGB looks fine, but the alpha is causing me to get these larger grey blobs in test comps...

Any suggestions?  I know you're here Alan, but I figured someone on the list might have a solution too.  Maybe I am missing something in my setup?
