Re: Unreal Engine 4 Lighting Units confusing, issues Candela to Lumens
You can't really judge the light intensity by whether or not it looks correct in the viewport until you expose for it. It being white is expected because you're using a much wider range of intensities that need to be accounted for. You can increase max exposure value to something really high like 10,000 or just enabled… -
sky luminance in a post process shader
Hello I'm working on an optoelectric night vision post process shader, its pretty cool and stuff but it has some ugly hacks none of the atmosphere nodes in the material editor that I've found give me all the elements of the sky so I'm masking and boosting the basecolor luminance based on the overall sky luminance and it… -
Lumen, volumetric fog and flashlights.
Hi! My scene consists of a dark environment, a flashlight and fog. pretty clichê. I’m using lumen for lightning. My issue is, when the flashlight is on, is has a nice effect on the fog, but it has a light trail when I move it around, I guess this is because of lumen update speed. I know I can up the lumen update speed in… -
Lumen Issue Sequence
Okay I have another issue...I'm trying to render my scene through lumen and I gotta say I'm having a very difficult time getting the render to look decent. Are there any suggestions on how to improve renders? Please help me it's driving me insane. Also, it only looks like this through sequence, in game it's fine. -
Lumen interior lighting
Hello, i'm working on my first unreal scene. It's an archviz interior using Lumen. I've been learning mostly from YT, official videos, and documentation, and even tough i still have a lot to learn i've reached a sort of impass because i don't know what else to change or check. This is what i have so far: (link to… -
Re: Is lumen really optimized for games?
The Lumen documentation states it's a "fully dynamic global illumination and reflections system that is designed for next-generation (current gen now) consoles" - so no baked lighting with Lumen. If you want to use baked lighting you would have to setup your project accordingly. The question whether Lumen is optimized for… -
Lumen and Ambient light
Hey, I know lumen is supposed to simulate how light works in real life. I'm working on a project where we are building really dark interior rooms and corridors, and the player will use a flashlight to look around, but I would like to have a minimum of ambient light so he/she can move around even when the flashlight is off.… -
Unreal engine 5 Lumen reflection problem
Hi guys, so I was experimenting with lumen on a project that I was finishing in UE 4.26, but I'm having a few issues. My main problem is about the shaders, this wwater shader is not reflecting at all in UE5, the first picture is in UE4 and the second on UE5. The reflections in the glass are also looking odd. Also I'm… -
Exsite scene and ue5 Lumen...
This is a scene that I created originally for ue4 using purely dynamic lighting. (https://ad67.artstation.com/projects/eaLGmD) This pic is from the imported scene in ue5 and using Lumen. So far I am very impressed with how Lumen works and how everything is well integrated....some issues exist that hopefully will be ironed… -

https://www.youtube.com/watch?v=yMTq4xPvxfk Hey guys!

In this tutorial I show…
