Greetings Everyone.
I have a problem when using Matte Object in Krakatoa rollout. Although i have increased the SuperSampling to get nice and smooth matte edge but i have no luck for it 
Here is the problem.
IT DOESN’T MATTER ANYMORE. I HAVE FIGURED IT OUT BY USING “OCCCLUDED LAYER PASS”
I was about to provide this link
docs.thinkboxsoftware.com/produ … matte.html
but you figured it out yourself! Bravo!
