I have been working on an external scene and have been noticing the way the background is interacting with my tree's, it really messes with the edge's, volume and clarity of the foliage. Attached are two renders at 100% the good one was rendered against a black background and the sky added in post and the bad render the background is rendered in frame.
I suggest placing both images as layers in photoshop and click back and forth to see exactly what I mean.
Is anyone able to explain to me what is going on and why it looks so bad ?
Cheers

I noticed that many tree assets looks unusually thin in Corona. Since i don't have any other renderer to compare to and i never do compositing i always thought it's just how it is, maybe asset creators do poor job, or something else, but now when i see your examples, it's obvious that something is not quite right and it would be good to find what's causing it and see if things could be improved.

We can check the scene, or you can just let us know how to reproduce it in a simple scene.
Bear in mind that the amount of "burning" of the sky into the foliage depends on the sky intensity. For example, if you would add a texture/solid color with an extremely high intensity, the amount of burning would also be extreme. Right now it's hard to tell what exactly is wrong.

Same issue discussed at length here https://forum.corona-renderer.com/index.php?topic=35500.0

I understand that having an intense light behind an object can create a harsh fringing effect. But take a look at the same shot rendered with a standard sun sky that I would say is not intense at all. The foliage is just as clipped as my other example regardless of intensity.
I think this really warrants further investigation or explanation since the outcome is really not desirable. I would like to render the whole shot in frame to keep my post work to a minimum.

For sure I agree 100%, I was just pointing out this has been discussed before and the blame was placed on Photoshop. Which clearly isn't the case here
