[1.7.10] Changing Icon on Rendered EntityItem

[Izzy Axel]

I have an item set up to switch icons with NBT, but if I try to change the NBT on the EntityItem instance created just before rendering it in a TESR, it's null, so it crashes.  So, how else would I go about changing the icon of the item for the render, and more specifically, changing it multiple times?

 

TESR

TileEntity

Block

Item

Inside the TESR, there's a commented out line that changes the NBT of the ItemStack in the EntityItem that's created for the purpose of passing to the RenderManager.  I want to change the contained Item's icon, but what I did there is throwing a NPE.

Yyyyep, I realized that when I woke up today, I was assuming that when I created the itemstack, the item got its NBT created, but that would only happen on the next tick.  Lesson here is, don't assume anything.
