RenderLayer does not preserve Alpha?

Hi all

we are trying to achieve to get a post effect not applying to the whole image. Therefore we use a render layer and add the postFX (like Glow) only to the parts of the image we need. But as i can see, Render Layer has no Alpha channel or the objects that render to render layer are not visible to root node -> View Layer Alpha… does this mean reander Layer only produces RGB but not A. correct?

Hey Urs,

I can’t replicated the same issue you are describing, could you send over your project file to for me to look at?



shame on me … i forgot to click the “alpha” Channel in the glow effect :-// Sorry for bothering

No worries - Glad you found the fix! :slight_smile:
