What I'm doing now works (use Rendering Presets and Batch Rendering to render the scene once with the Output box unchecked and then switching to a different preset where the Output box is checked in order to render out the Glare as an Overlay Only image), but there must be a way to render out the glare on it's own pass.
I tried working with render elements, but it didn't look like what I wanted was there - unless I missed it.
I also tried using Lens Effects under the Environment/Effects controls and was playing with a combination of File Output and Lens Effect > Glow, but, again, unless I was doing something wrong, it wasn't working or doing what I thought it would.
Any suggestions? I know there must be a way to do this without rendering the images twice - at least I hope - but I just can't seem to figure it out.
Most of my work can be rendered at night while no one is around, but should something need done quickly for a last-minute meeting, the ability to render the scene once would really be clutch.
Thanks in advance for any help!
