Fixing Lighting Errors

[neiromaru]

My latest project involves massive (the biggest is 128x128!) panels of colored wool and glass with space in between for a dispenser to pour energized glowstone to invisibly light up the panel. (the glowstone doesn't render behind the stained glass)

Unfortunately, even when the glowstone is turned off, and there are no lighting sources anywhere nearby, minecraft decides to render big, random areas as if they're fully lit. I've tried pouring water down to cause a block update, but that doesn't work.

The only solution I've come up with is breaking and replacing the affected blocks. But since the errors are random, and the panels are so huge, this would require placing and programming several thousand turtles to automate, and I shudder to imagine the lag spikes that would be caused by simultaneously breaking and placing so many blocks.

So, is there some other way to fix these lighting errors? or do I just have to deal with it if I want this design?

Edit: This is on an FTB Unleashed + Gregtech server.

This sounds like a fairly vanilla rendering problem. Have you tried using any of the various mods that affect lighting to see if their renderer fixes your problem? (optifine, various shader mods, etc).

I used to have optifine, but removed it because it was causing textures to rapidly flash white.

And I'd like it to look nice for other people on my server as well, without requiring them to add a shader mod.

It's a Vanilla Lightning bug, there isn't much a mod can do about it.

Someone mentioned the other day that the bug is supposedly finally squashed in the 1.7 version. We'll see, we'll see ....

I knew it was a vanilla bug, I was just hoping that someone had figured out some FTB trick to force the game into reconsidering it's lighting buggyness.
