As described in the title, when

"random animal textures" {
B:"Enable Pig"=true
}

then randomly completely black pigs spawn with only their eyeballs staying white. I dont think this is intended because it looks very out of place.

Encountered this problem on Quark-r1.5-130.jar in combination with AutoRegLib-1.3-20.jar.
According to your changelogs this still might be a problem in the newest release version.

Maybe you just remove the completely black version or more likely recolor it a little bit brownish to resemble more of a wild boar.

That might have something to do with the lighting

Pretty sure that's just one of the texture options...

@renadi is right, but the texture definitely needs some changing.
