[solved] alpha help! (white fringes around trees)

[markfouronefour]

Hi there

I hope you can help me. I’m losing the plot here!!!!


I have rendered an image out as .EXR and loaded it into Afinity photo.

Then, I used the alpha channel pass to remove the sky from the beauty. All good.

When I drop a background in behind I still get the white lines around the trees.

How can I fix this?? Is my alpha set up wrong?

Is this a corona thing or an PS/ Affinity thing??

cheers

Have you tried using the 'Direct Visibility Override' in the scene settings? If you override it to black you should get a better Alpha channel.

That's what worked for me as I was having the same issue as you.

Try to render selected objects only in exr-File, this schould make a perfect mask.
pleae look at the example pictures.
on the right hand you can see how i comped them.

Please support me to convince Ondra to take selected object render pass in render Elements it would save many comp time and money.
