Hey everyone,

So I am trying to render one of my ModBlocks on a custom GUIScreen. The problem is, I have it rendering, but it extremely dark in the GUI. Rendering items looks fine, but the block doesn't. I have tried using standard Minecraft blocks, such as stone or obsidian, but still the same thing. Here are the important bits of my code. (PICTURE BELOW)

@Override
public void drawScreen(int mouseX, int mouseY, float partialTicks) {
	drawDefaultBackground();
	super.drawScreen(mouseX, mouseY, partialTicks);
	ItemStack icon3 = new ItemStack(ModBlocks.tin_block);
    GlStateManager.pushMatrix();
    {
        GlStateManager.translate(centerX + guiWidth / 2 - 16, centerY + guiHeight / 2 + 24, 0);
        GlStateManager.scale(2, 2, 2);
        Minecraft.getMinecraft().getRenderItem().renderItemIntoGUI(icon3, 0, 0);
    }
    GlStateManager.popMatrix();
	drawTooltip(icon3.getTooltip(mc.player, false), mouseX, mouseY, centerX, centerY + 40, 16, 16, guiWidth, guiHeight);
}

private void drawTooltip(List<String> tooltip, int mouseX, int mouseY, int posX, int posY, int itemWidth, int itemHeight, int guiWidth, int guiHeight){
        if(mouseX >= posX + guiWidth / 2 - itemWidth && mouseX <= posX + guiWidth / 2 + itemWidth && mouseY >= posY + guiHeight / 2 - itemHeight && mouseY <= posY + guiHeight / 2 + itemHeight) {
            drawHoveringText(tooltip, mouseX, mouseY);
        }
    }

(Indents messed up...)

Picture:

Try things with lighting, like:

 

GlStateManager.disableLighting();

Minecraft.getMinecraft().getRenderItem().renderItemIntoGUI(icon3, 0, 0);

GlStateManager.enableLighting();

I  have already tried that, sadly it doesn't work

Try using RenderHelper.enableGuiStandardItemLighting() / RenderHelper.disableGuiStandardItemLighting().
