In version 1.12.2-1.10.24 of the mod, aquamarine shale and starmetal ore look really weird, with black and white "shadows" above and below the ore parts of the texture. I have tested this with and without optifine, and it makes no difference.

Now what's especially strange about this is the fact that as items, they look completely normal

Mod list:

Judging by the lack of prior mention, I'm assuming it's an issue being caused by another mod, but I'm not sure which mod(s) would be causing it

optifine

As I said, I tried it WITHOUT optifine and the result was the same. @HellFirePvP

In other words, you didn't read the full report, did you?

I have tested this with and without optifine, and it makes no difference.

I'm gonna test again to see if it is actually optifine or not. (I am aware that optifine tends to break many things)

Alas, my testing was erroneous, it is indeed optifine causing it. Sorry about the hassle :)
