Weird artefacts on transparent Png? Sky replacement & rendering.

[Franzi von Fragenfeld]

Hello everybody,

I've got an issue with an evening scene of mine.
I have taken a photo and removed the sky (with refine edges).

This is done as to have the HDRI background visible when rendering. There are different lighting sceneries I need to use.

In daylight it looks ok. because the sky is bright, but when I render the night image in Blender I have these "glowing branches".

To make it better visible here I put a black layer behind the PNG with the transparent png. The black area of the PNG on the right is the transparent area.
Left is the rendered result, right is the png in Affinity photo.

How can I get rid of that glow? i like to do that in the transparent png before rendering.

Thanks for your help.

Hi,

What render engine gives this result? Eevee, Cycles or both?

[Franzi von Fragenfeld]

Sorry, I just got back.

Cycles.

And by the way I use the very latest version of Affinity Photo and E-cycles 2.90.

Ok. Got it. My mistake.
There was a emission node accidentally switched on in the backplane image.
Just set it to off and things are better. Tricky part, than the backplane is pretty dark.
But I guess thats more of a Blender issue.
