BuildCraft version: 7.99.17
Forge version: 14.23.4.2707
Link to crash report or log: N/A
Singleplayer or multiplayer: Singleplayer
Steps to reproduce: Run BuildCraft alongside Optifine and then look at any oil related item.
Additional information: Oil related items aren't rendering the oil inside of them (buckets, cans, etc.) I am running BC alongside a bunch of other mods, but the issue still persists when just BC and OptiFine are installed, and once I remove OptiFine, all of the textures render correctly.

Pictures:

It's just a large, black mass:

Close up:

Buckets, cans, capsules, and florbs all displaying as empty:

@vrork, but I don't have Aetherworks installed so how could that be the problem? The only two mods installed while the issue occurs are OptiFine and BuildCraft.

It seems that BC is having problems with texture interactions for the oil. It has a weird bug with Aetherworks that causes a problem with the textures too. I think they need to see how they are "making" their texture be used

@vrork, what's Aetherworks?

I am not saying its Aetherworks only fault. But its another mod that BC has problems with textures when interacting

looks to me like an optifine issue, it changes the way things are rendered and doesn't seem to like our swapable sprites for animations

I have seen the exact same problem, the textures become even worse when other mods are involved, however I am still testing to see what mods are doing so and why. Anisotropic filtering from optifine seems to intensify the broken oil textures as running oil seems to be glossy and with edges when it's a liquid.
