I use Cycles. The main goal is to render different objects from various scenes into separate files using alpha mask. It’s necessary to ensure that in future pictures do not overlap, when images superimposed out of order. All fine, BUT there is one nuance:
Between layers (images) there are gaps (holes).
I have found solution for similar problem but for internal render. There had to disable antialiasing.
Please advise how is it possible to remove all gaps (holes)?
