Masking Q

I am trying to figure out how to integrate the mask element for the stairs. As you can see the third ball is under the stair and I have the mask ready but unsure where to plug it in. I have provided the script and image for reference.

Thanks everyone.

if you add another Copy-node (after that over below Copy2) to copy the red from the mask into the alpha and a Premult after that...that should do the trick.

hope that's what you meant


cheers

Edge Blur Intersecting Masks?

I am now trying to find out how to use the edge blur on intersecting masks. I tried to split up the mask in red and green channel, but its still sharp at the intersection. Now if it's 1 mask element with shuffled red and green it sort of works but as you can see in the second image it's picking up the background when blurred.

Please help someone.

---------FIX

Anyone interested. The fix was to change the plus to "mask" after the shuffle. Next change the edge mult setting in edge blur to 10.
