In order to get started in Compositing, I want to create PNGs of different layers (3DView Header Layers) and then bring the PNGs in separately on image nodes. But I get a grey outline around each object in the PNG images (clearly visible in the right tree).
I thought I was supposed to turn on Full Sample in the Anti-Alias SubPanel of the Properties Panel to remove those outlines…but I get a “Full Sample AA not supported without 3d rendering” Error when I try to render.
Is there a list of Errors that will help me understand what this error means? I am using 2.62 with Blender Internal Engine.
