Thanks a lot, Daniel. I was looking for a solution to my project for around 5 hours. The command "r.lumen.screenProbeGather.screenTraces 0" solved my problem.. It is fascinating that no one mentioned this in their tutorials but they had no problem using emissive light.

this is cool, it would have been helpful if you did a comparison between using real lights vs this technique and show the fps gains, but other than that, awesome demo.

Thanks, nice and clear tutorial. So I wonder why its not working for me (UE 5.3.1). The sphere behaves just like yours but casts no light into my scene. It becomes bright to the eye as I increase intensity yet casts no light around it.

I loved the trick of adding Temp in an emissive material, but I don't think they should replace lights in a scene. Emissive are still too noisy and probably way less performing than lights. They also miss a lot of parameters (like barn flags and such).

Great tutorial! Do you know a way I can make these elements invisible in reflections? With my current setup looking into a window I can see all the additional geometry with these shaders applied. This is even when they are hidden in game.

Currently I have not! It’s been bugging the hell out of me but it is tied to hardware raytracing which makes sense as any light that has specular intensity will have a similar effect

Is there any downside to using this? It seems like you could (or should) just be using emissives instead of classic lights like spots and omnis.Also, doesn't scaling the emissive meshes make the intensity higher?

If you press ''G'' and enter Game View, it goes out. But if you want to use the Game View without erasing it, just leave it as ''Visible" and activate an option further down called ''Only Owner See'' I ended up discovering it by chance. 😅😁

The question - does it really cheaper then point light? What do you think guys? Did anyone test this? I mean in terms of performance.
@DanielLanghjelm
Жыл бұрын
Hey! It is :) the reason is that it’s based off of distance fields and contributes to the Global illumination of the scene as opposed to actually lighting it if that makes sense. Any shadows created are also distance field based. In comparison dynamic lighting is very expensive due to fully dynamic shadows being calculated. Hope that helps

@@DanielLanghjelm Thank you very much! It’s important for me because the baddest thing is lumen, and it hits so bad on the performance, even though the geometry is optimised as possible. So I needed to get the alternative way to light things and get less fps hits:D

the emission material would be much easier without the temperature node.
