Hey Ahmet,
I've been trying to export out a separate volume pass with other light passes.
When the medium/fog is activated activated in the environment tag, the light passes and their alphas become slightly transparent where the solid object is, and the background where there are no objects become more opaque.
This also occurs on the main pass, but not the diffuse or reflection passes
Is this the correct behavior?
I'm probably missing something, but compositing these in AE is not providing the same result as the picture viewer.
I've attached some screenshots and a scene file. Please let me know if I've overlooked something.
Thank you!
