the first one is a visual bug, the second one happens with some armors, for example with the magma block armor or the prismarine armor

there's another bug that happens only with the leaves armor, those armors are gray

One upping this, on the most recent snapshot [26-12-18] the same bugs still appear, Prismarine Helmet doesnt appear on player if the rest of the set is equipped, equipping the set of Magma armor disables visuals on everything but Boots.

Leaf armor is still gray (this has to do with the default texture file being gray and Minecraft using some sort of code to render their shadings Im guessing)

And there is still slight little visual glitches in any modded armor, (potentially something with two separate textures being loaded?)
