Aside: The bat's animation plays super fast, looks like a hummingbat.

What's the name of the blockwhich is connect to ur pipes and tanks?

I kinda see it. This is likely cause of the Entity Renderer from Minecraft. Usually entity renderers are rendered at a seperate time from tiles so MC code can be sloppy setting GL states back. I'll have to dig into their code and see what they left open and close it myself

Can you please point out exactly what block/object I should be looking at? I see nothing wrong

@pauljoda the mob pedestal with the bat is white the other upfront are grayish

I guess I still don't see it

@pauljoda shouldn't this two be in the same color? http://prntscr.com/a5z7p1

Closing for now, might not be us but I'll keep an eye on it
