Creating a Spotlight with a Wider Source Radius than a point in Path Tracer and Volumetric fog?

Hi everyone,

I’m working on a project in Unreal Engine 5.5 using the Path Tracer and need some advice on achieving a specific lighting effect.

I’m trying to create a spotlight that doesn’t originate from a single point but instead has a wider source radius, like a disc or larger area. I’d like the light beam to show up and interact properly with volumetric fog for a cinematic look.

In Redshift, for example, you can assign a light to a disc mesh to get this effect. Is there a way to replicate this in Unreal Engine’s Path Tracer? Any tips, tricks, or insights on achieving this would be greatly appreciated!

Thanks in advance for your guidance!
