Here's a gfy representation of the problem I'm having:

 

 

So basically I have a TileEntitySpecialRenderer, and I have it so that the item that is in a specific slot of the TileEntity is rendered on the block model. The problem is that when I enter the world the items are not rendered until I click the block and open the GUI, then the items appear. What am I missing so that when I load the world the items load without having to click the block. I'm guessing there's something to do with the TileEntity?

 

Here's the code for the TileEntitySpecialRenderer:

EDIT: Tile Entity code: https://github.com/Raizunne/Miscellany/blob/master/main/java/com/raizunne/miscellany/tileentities/TileEntityAdvReactBrewer.java

 

Thanks in advance for the help!

Yup that did it! I used a tutorial from here: https://countrygamer.wordpress.com/minecraft-tutorials/tileentityspecialrender-using-the-te-to-update-rendering/

 

It was a little outdated, and it caused me GL11 problems, but moving the stuff that the tutorial tells you to put in the TESR in the block's updateTick will do.

 

Thanks for the help!
