Lighting Bug - adjacent faces lit differ Created 16 years ago2008-08-12 12:14:59 UTC by Jinx

Didn't find any help on Snarkpit so I thought I would give you guys a crack at this one

Having some issues with a lighting bug. I have tried lowering the -chop, removing nearby light entities or adding them, changing the number of bounces, adding ambient light, making the arch brushes entities vs world brushes, and remaking or rotating 180 degrees etc. the arches. No luck.

It seems to only happen with arches that are in a room where light from the sky brush can reach them, though...?That's the bug- you can see a 'ghost' of the arch around the doorway.It is the doorway over to the left that is in the pic, but several others in the map have similar issues.

Here is the map's profile (pics and download of the last beta) on Snarkpit if you want a closer look:

Any help would be appreciated. Think I'm going to focus on finished everything else on the map since this has me pulling my freaking hair out!

What am I supposed to see? (Except for a misaligned texture...)

Yeah, i don't see it either.
I say mark it with an arrow/ellipse.

Seriously guys, you can't see it?
That's not an align problem, it's obviously darker than the other faces.

I have no solution for it myself.

Yeah, the brushes making up the arch of the door are darker. The textures are not misaligned. I marked the corners of the distortion in this one and boosted the contrast to make it more obvious:Open it in the bigger window to see the full size version.

He means look around the arc. Its darker and you can see where the arc brushes meet the other brushes.

Are the dark parts solids or brush entities?

I have tried them both as solids and as func_walls, it doesn't seem to make a difference :/

I might try eliminating the light_environment entirely to see if that is part of the problem.

did you manually line up the texture that the darker parts are on? Sometimes if the texture isn't uniform with the ones around it, it can cause problems in a few ways are far as lighting goes.

I can re-check. I generally select all the textures I want align at the same time, then align them all at once like they are one big surface.

What happens if you copy the arch in question into a new map and run that ingame? If the dark parts are still there, try a different texture, or upload it to the problems maps vault so we can see if we get the same problem. Im very curious...

I would agree with Rim. If that's not the trouble i really don't know. Awesome-looking map btw! = )

Which version of ZHLT are you using? Tried using an older/newer version?

okay, I don't quite get this but I managed to fix it. I took an arch that didn't have any issues and cloned it to replace the problem arches. Then I manually adjusted the textures on the arch to match the surrounding wall textures, but I only selected the arch while doing this.

Not sure what the deal was, but at least it seems to be fixed (for now..)

Thanks for the suggestions and compliments. I'll try to come by more often, not to mention make my maps available here
