I downloaded this particle pack called ‘M5 VFX Vol2. Fire and Flames’ from the marketplace and used some fires in my level and it seems like the light from them just doesnt get stopped by any surfaces in its way. The surfaces are still being lit but stuff behind them also. Tried checking ‘cast shadows’ but that did nothing. Does anyone know what might be causing this?
here are some screenshots
It looks like it’s not just particle systems, but point lights also, take a look in the blueprint.
You can hack it to give an option to turn them off, or make a version with them…
I dont want to turn them off. I just want them to interact properly with their surroundings.
In this instance, turn the light off.
It will work how you think it should. More or less.
If you want the light to filter the doors, and the doors aren’t movable, then you can create a custom light profile to achieve the effect…
I think the lights are on the wrong side of the door, that’s the problem.
What do you mean the wrong side? Whatever side they are on they should cast shadows on the other one and not pass through it.
I think the point lights are on THIS side of the door, that’s my theory…
oh no, the point lights are being emited like particles from the emiter. its just that they arent casting any shadows on anything, even when i turn on ‘cast shadows’
No, nearly… 
What I mean is: I think this is a BP containing an emitter? If that’s the case, there might be ACTUAL point lights in the BP. Maybe they are on the wrong side of the door.
If it’s light from the particles not casting a shadow, have you checked this stuff?
This is one of the fire assets inside the m5 vfx vol 2 filre and flames pack. Im not sure if its a blueprint or just a ‘material’ but for particles. I dont see anything that has to do with lighting. I tried searching ‘light’ or ‘shadow’ or ‘translucent’ in the bottom left but i didnt find anything.
Ah, Cascade.
So you just drag the emitter into the scene, there’s no blueprint containing the emitter?
It’s a free pack, you should have said I will check it out…
Yeah, I didnt know, thanks for your time though, I appreciate it.
You see all these things that look like bulbs?
Those are lights. It’s spawning point lights. If they’re anywhere near the door, it will illuminate the columns.
I have placed it back a bit, then it’s not too bad:
But if you want to get rid of the totally, you have to stop it spawning lights. I will have a look.
Ok I see, yeah I dont know how to do it but yeah take your time, this project is for fun anyway. Its fine if you cant find anything
Omg ok this is amazing. If i select this block i can enable shadow casting on the lights. Thank you so much for your time, this literally saved my project!

So many point lights so close together?
How isn’t the engine not throwing a fit over this, and how did the product make it past marketplace QA?

They’re not actual point lights, but a sort of particle light, which apparently also casts shadows…
