[1.7.2] Need help with custom glass!

[DarkRattle]

So first time using forge and the thing is my glass is working BUT in my hand it's not showing as it's texture. It's showing as a full black block. I don't know why. Here are some pics

here is my code:

 

public class BlockBallisticsGlass extends Block {

public BlockBallisticsGlass() {
	super(Material.glass);
	setBlockName("glass_ballistics");
	setBlockTextureName(DarkPack.MODID + ":" + getUnlocalizedName().substring(5));
	setCreativeTab(CreativeTabs.tabBlock);
	setStepSound(soundTypeGlass);
	setHardness(1.0F);
	setResistance(1000F);
}

public int getBlockTextureFromSideAndMetadata(int i, int j) {
	return 9;
}

public int quantityDropped(Random r) {  
	return 0;
}

@SideOnly(Side.CLIENT)
public int getRenderBlockPass() {
	return 1;
}

public boolean isOpaqueCube() {
	return false;
}

public boolean renderAsNormalBlock() {
	return false;
}

protected boolean canSilkHarvest() {
	return true;
}

}

Hi

 

From memory, items in your hand are rendered with alpha blending turned off.  So the partially-transparent parts of your block are rendered as totally opaque.

 

You could get around this by implementing an ISimpleBlockRenderingHandler and drawing your icon with alpha blending enabled

eg

 

http://greyminecraftcoder.blogspot.com.au/2013/07/block-rendering.html

 

and

    try {
      GL11.glPushAttrib(GL11.GL_ENABLE_BIT);

        GL11.glEnable(GL11.GL_BLEND);
        GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

     // do your rendering here
    } finally {
      GL11.glPopAttrib();
    }

This was the case pre-1.7. Look here: http://puu.sh/8Sq6V.png

Either there's something missing or the vanilla renderer has exceptions for specific blocks (like the stained glass)

 

EDIT: looking at it again, if the renderBlockPass is > 0, it uses blend (look at the doRender method, line 124 in class RenderItem)

 

 

BTW: Always add @Override to methods you intend to override! It shows you errors if you, for example, made a typo somewhere or the method signature changed.
