Rendering items in 3D

[zacpier]

I am using an [glow=white,2,300]ISimpleBlockRenderingHandler[/glow].

 

public class RendRobotTier1 implements ISimpleBlockRenderingHandler {

public void render(IBlockAccess world, int x, int y, int z, Block b, int model, RenderBlocks r) {
	b.setBlockBounds(0.15F, 0, 0.15F, 0.85F, 1, 0.85F);
	r.renderStandardBlock(b, x, y, z);
}

@Override
public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z, Block block, int modelId, RenderBlocks renderer) {
	render(world,x,y,z,block,modelId,renderer);
	return true;
}
@Override
public boolean shouldRender3DInInventory() {
	return true;
}
@Override
public int getRenderId() {
	return RobocraftRenderProxy.t1BotRender;
}
@Override
public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) {
	// TODO Auto-generated method stub

	//render(null, 0,0,0,block,modelID,renderer);
}
}

 

As you can see, I have commented out the render code for "renderInventoryBlock".

I know that it crashes.  It crashes because of RenderBlocks trying to get light values.

 

So how do I render an item in 3D?

 

I'll give the best answerer a cape.
