You can't help it, light blending happens because of the way global illumination works. The only way to remove those artifacts is to disable global illumination.

Re: Light bleeding [help].

Use the /nogi (no global illumination) material to stop light from bleeding. It's a Tesseract-specific material with a “coffee”-ish colour. It lets you disable global illumination in specific areas; try putting it in your whole room.

Negative lights were removed from the development version and will not be available in the next release – they didn't always work anyway, they worked in a random way depending on configurations.

I'm not okay with this.
That's why Tesseract is fun and it worked pretty well to me.

I know. All the other players I played with didn't have bugs with them tho. So that's why I think it's not a large scale problem. Beside that, I wonder how many reported these "bugs".

Re: Light bleeding [help].

Does other solution appear since 2014? :)
I run into the same issue while trying to create my map but "/nogi" option is actually not what i'm looking for, because the room is not closed-space:

Maybe I can somehow reduce the side-effect of GI work?

Thanks in advance.

Re: Light bleeding [help].

That's not GI bleeding. do you have adequate geometry blocking the corner where light comes through?

I've been away for a while too, if /lighterror is still a thing, set it to 1.

Thanks for the responce, RaZgRiZ, I will try lighterror command.
I've just realized that I built walls  separately by extruding each from the floor instead of  building whole building as one block and then cracking inner room into it, but in this case I do not understand why floor was lighten near walls.

Apologies that i can't help more until i get a keyboard that isn't missing 5 keys :P

When I get a replacement I shall join you in game to get myself re-acclimated and help you further with your issue :)

To be clear however, how you erected the walls makes no difference to this slight "bug". Tried /remip as well?

It's ok :) ,  I myself far away from the computer so still have not checked "lighterror"  command.

And thanks for you proposal, I will ask your help if nothing helps.
I didn't tried a /remip, at least if it's not executed when pressing K key in edit mode to do "Lighting optimizations"  (or smth like that,  I do not remember exactly)

Ya GL is kind hacky and it does do strange things with thin walls. You just have to bulk up your walls and it will go away

Use the "nogi" material on the area you don't want to receive global illumination.

I've tried but it did not solve problem...

Frankly speaking, I've only tried it for the entire room but did not try to assign "nogi" only for areas where the problem occurs, thank you for the idea.

It almost solved the problem, only some tiny illuminated area along non-thick walls joints left and they are really tiny and almost not noticeable.

Re: Light bleeding [help].

Do you have any lights on the scene.

Can you bundle up the ogz (map file) and upload it here. I may be able to tweek it if I have the actual file.

Or, you know, all these times you've gone on IRC, you could have asked me to see the problem and help you. Just saying.
