Adding an "outer glow" effect to an object

[DrJay]

Hi there,

i'm trying to achieve something like this:

What i've tried so far was using a Black Body Emission in the Emission Channel of my material but this doesn't work for me. Is there a way to make this happen in octane or is "postproduction" the key in this case?

Thank you in advance for your efforts!

kind regards
René

Is this what you are talking about?

and you can render it as a separate image using "post" seting in Render Passes.
This will give you the ability to control the strength of the glow in post.
