All obelisks don't seem to render correctly when in the hotbar. (http://i.imgur.com/Z43sUYg.png)

They do seem to render fine when the inventory is opened (http://i.imgur.com/nHco3f2.png)

Which version of Ender IO?

I can observe similar issues:

How to reproduce

• switch to creative game mode
• drop Obelisk in hotbar
• switch between tabs in creative inventory or search for something

EnderIO 2.3.0.420
EnderCore 0.2.0.31
Forge 1558

Oh I hate item rendering sometimes. It is like driving a Formula 1 car with a blindfold on a beach. You never know what hits you, could be a parasol, could be a seal, could be a Navy Seal.

What happens here is that some other item that is rendered before disables transparency completely. So the box that is there for the bottom texture has all its transparency rendered as white.
