this png need to download to see clean.
He say “Set the mask to the red channel and it should work”
but my merge node doesn’t have Color.R.
At first I used Z depth in two exr and then converted to Black&White, but this shows that it only has RGB channels,it alpha channel is all white.
I tried using “chromakey” node to make black transparent but not working.
I need to change to alpha to use as a mask… How can I do this?
Thank you all first.
