Hello, Im doing a course on Udemy by Vince Petrelli. The course like his other courses has been great but I noticed that his Niagara VFX give off light and reflect in the environment whereas mine do not with Lumen enabled.
Im using unreal engine 5.3.1 but I also tried this in 5.2.1 and got the same result.
Your post process effect seems to be setup properly.
How strong is your emissive material? If you increase the strength will it increase the light casting? I would look closer at something like this: https://www.youtube.com/watch?v=AO5I0yJEcPY
The issue is that reflections work with SSR but there is no reflections or GI from niagara particles even with emission output multiplied by 3000 in material.
Not sure why this an issue with lumen GI which should work perfectly well with emissive material
