[1.7.2/1.7.10] Item rendering glitches


Tyron

Recommended Posts

I'm in the process of upgrading my mod, first to 1.7.2 and now to the forge beta version of 1.7.10. In both versions I'm getting rendering glitches where the transparent portion of the item is rendered partially pink, partially white. This only happens for the rendered inventory item, the rendering of the entityItem and equippedItem are both fine. I guess some generic GL-Setting is missing. My rendering code worked just fine in 1.6.4.

 

Here's an example of the glitched gfx:

Here is my inventory item rending method - in order to save me from creating hundreds png graphics, I'm drawing 2 images over each other:

@Override
void renderInventoryItem(ItemRenderType type, ItemStack item, Object... data) {

        GL11.glDisable(GL11.GL_LIGHTING);
        GL11.glDisable(GL11.GL_CULL_FACE);
	EnumButterflies butterfly = ButterflyMania.getButterflyOfItem(item.getItem());

	if (butterfly != null) {
		ButterflyMania.loadTexture("/textures/items/smallbutterflies/" + butterfly.code + ".png");

		GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
		this.renderTexturedQuad(0, 0, 0, -1, 16, 16);
	}

        
	String texturename = JarType.getTextureName(item.getItemDamage());
	if (texturename != null) {
		ButterflyMania.loadTexture("/butterflies/" + texturename);

	}

	this.renderTexturedQuad(0, 0, 0, 0, 16, 16);

        GL11.glEnable(GL11.GL_LIGHTING);
        GL11.glEnable(GL11.GL_CULL_FACE);
}

Ok, fixed it with following gl settings, incase someone else runs into the same troubles

 

        GL11.glDisable(GL11.GL_LIGHTING);

        GL11.glEnable(GL11.GL_ALPHA_TEST);

        GL11.glEnable(GL11.GL_BLEND);

 

  [render item]

 

        GL11.glEnable(GL11.GL_LIGHTING);

        GL11.glDisable(GL11.GL_ALPHA_TEST);

        GL11.glDisable(GL11.GL_BLEND);
