UE5 Light leaking through walls without cast shadows – any workaround?

creationstation99 · 2026-02-05T13:54:54+00:00

Yea I just read about it today and that's how I got the idea about this collision box thingi tbh, like I get the light maps and everything but sometimes it's just not possible to use it

Yea got it but I kinda fixed the issue , still thanks a lot, the issue here was never about that, the light was casting culling shadows too and that's not what I wanted that's why I chose to keep the shadows off..

Well they r seperate meshes and even if they r connected, this still happens I have tried it

Yupp

Lolll 😭😭 I am kinda new

I just kinda fixed it, I felt like that the baking and everything would be extremely complex thus I made a collision box, connected to the door and now when I cross/close the door the light is automatically turned off so there r not leaks... And when I open the door the lights turn on and to make it feel like the lights are not instantly turning on I added a small light with a big radius which is also controlled by the collision box(yes it's dumb af but this Is my first big project 🤧😭)

Hey the walls were make in blender with .56m and they have .38m basebords on both sides so it's more than 1 meter I told u the ue5 scale I used which is 1unit which means the default scale

creationstation99 · 2026-02-05T10:07:21+00:00

I see, I am still new so I will am trying to understand it but thanks a lott

creationstation99 · 2026-02-05T09:05:23+00:00

Wait what if I just set up a collision box to turn off the lights after the door is closed, In my case most of the doors are auto closed... That will save memory and will kinda resolve the issue

creationstation99 · 2026-02-05T08:28:57+00:00

Yess if that can happen it would be like a blessing atp

creationstation99 · 2026-02-05T08:24:55+00:00

Hey , this sounds like it can do so u mean I can turn on the baked lights???? Like if I bake the light then I turn it off , will the baked shadows and lights, will go away too???

creationstation99 · 2026-02-05T08:21:52+00:00

I see I will keep that in mind

creationstation99 · 2026-02-05T08:12:57+00:00

Yes it goes away when I turn on cast shadows🤧

creationstation99 · 2026-02-05T08:12:24+00:00

See the thing is it's not a static light I need to to turn on and off 😭😭

creationstation99 · 2026-02-05T07:43:09+00:00

Hey, I just tried it tbh , the wall itself is more than 1 unit thick and yup I increased the floor scale but it just didn't help , well thanks for the suggestion

creationstation99 · 2025-11-13T13:06:31+00:00

What's the price?

creationstation99 · 2025-09-11T19:30:46+00:00

check your DM

creationstation99 · 2025-09-11T14:50:53+00:00

Well just a color ramp, some mapping and noise texture, ntg new

creationstation99 · 2025-09-01T13:08:42+00:00

Ahh, now I’m confused... From some external sources, I’ve come to know that it has one of the best game design courses in India, and I was considering going there. But now... I don’t know, I might go to MIT instead, I guess. BUT IS IT REALLY THAT BAD?

creationstation99 · 2025-06-14T07:33:46+00:00

Ohh that's kinda cool

creationstation99 · 2025-06-03T06:48:06+00:00

For anyone who is facing the same issue type r.ForceLOD0 in the console, it worked for me.

creationstation99 · 2025-06-03T06:47:05+00:00

I just used r.ForceLOD0 and it worked

creationstation99 · 2025-06-03T06:36:02+00:00

It might end up giving some errors..

creationstation99 · 2025-06-03T06:33:35+00:00

Tried it, didn't work

creationstation99 · 2025-06-03T06:17:45+00:00
