I have a scene with an array of cubes. I am using Cycles to render.
I want to use the Mist effect to make the cubes in the distance fade away.
I want to render this array with a transparent background.
When I combine the Mist output (from RenderLayer node) with my render, I see a fringe. The edges in the alpha channel and the edges in the Mist pass don’t quite line up (I am guessing). It looks like the Mist pass has edges that go out farther than the edges in the alpha channel.
What are some good ways to have my mist, yet have transparent background? I tried figuring it out on my own, but I’m not getting anywhere.
I don’t think it’ll help to attach my blend file, because my own ideas for compositing the mist with the alpha-channeled render aren’t working, and I’m flailing about here. I meant to try using the alpha channel to mask the Mist pass, but I don’t think I figured that out.
