Hello folks,

I need some advice to fix a problem I have with the image attached.

Essentially, I use a caulk_shadow brush to alleviate a lighting leak, but it's not fixing the problem I attached. I should say, it fixed it in some areas but not in others.

What's the best way to fix this?

Thanks in advance...

Hi - try light occluder (i believe...it has been a while)

Thanks for the post stryder, I looked at the tools brushes & there isn't a light occluder in radiant.

I tried creating a light_portal in the room with the light leak & that didn't work- I also used the back of a brush as shadow_caster...these didn't solve the problem either.

Hi all, I'm revisiting this post because I've rebuilt the rooms with lighting.

Before, I created the walls to be perpendicular to the floor- I've now beveled the floors & walls hoping that it would fix the problem.

It still hasn't, does anyone have any tips on correcting this problem???

Thanks again...

This once was quite a common question, it has a lot too do with the light entity, if the radius of the light hits the walls it tend to leak under them on compile.

You need to reduce the radius of the light and make sure the rings around the light (on the 2d grid) do not touch the wall.

thanks mystic,

I upped the radius of the light since I didn't want to raise the intensity- when I did that, the room ended up being too bright with extremely high contrast (it's a small room).

I don't want to have to add extra lights to achieve the effect that I want but I may have to...

Another thing to try or consider is to make sure that your floor is not just one brush. Sometimes on a larger flat surface like that you will get light traveling along the whole brush and it will occasionally bleed under a wall. You can see this at ceiling height too.

I dont like to make more brushes than is necessary but sometimes you have to do this. In the image that you provided try cutting the floor right there and dropping the wall so that it is below the level of the floor. The wall should then block the light bleeding plus the floor is not catching the glare or light path that it use to pick up.

Worth trying at least. Works for my maps and I never get bleeding.

thanks for the tip ray,

I actually did try that method as well; when I beveled the wall, it actually extended past the hallway floor by 8 units.

This didn't fix the issue for me- mystic's suggestion seemed to have fixed the problem I was having...
