Hello, I'm just wondering if this issue has been completely fixed yet? When looking in the eastwards (also north) direction, the facades render perfectly, but in the south (and west), not so good. This is not an optifine issue as it still happens without OF. Why would two sides render ok, but other two be messed up?

This issue really upsets me, as I love the idea of facades but avoid them due to the ugliness.

This is an apparent bug in the minecraft render engine. Unfortunately, I could find no solution that didn't make the other six sides look worse.

I have confirmed with other modders that this is indeed a Minecraft bug that they have also encountered.

Bad, stupid Git don't close this..... I only mentioned this issue, not closed it. -.-

ok thanks for the info. Is it known whether it is affected by different forge versions?

I doubt it. Its in the core render code, a place Forge dares not to tread.

There are two issues, the texture coordinates are off in those directions and the ambient lighting calculations are off.

No ownership has been taken on this one over the past 4 months, so I'm closing it. Feel free to discuss further on http://mod-buildcraft.com/forums/index.php?board=2.0, or to find a champion to work on a fix.

OpenComputers fixed the bug by writing custom face rendering functions.
