I am making an "echolocation" helmet that shows wireframes around specific nearby blocks when you wear it (mostly ores).  I have the helmet detection code, but when I render wireframes they are obscured by the intervening blocks (I want them visible through those blocks).

 

I tried using both `RenderSystem` and `GlStateManager`'s methods `disableDepthTest` and `disableCull`, in all combinations, but none of them produce this effect.  How can I make my changes visible on top of everything else?

 

Code:

@SubscribeEvent
public void onRenderWorldLast(RenderWorldLastEvent event) {
    // only run if wearing helmet
    // if (!echolocation_active) return;
    ActiveRenderInfo renderInfo = Minecraft.getInstance().gameRenderer.getActiveRenderInfo();
    Vector3d pv = renderInfo.getProjectedView();
    double x = pv.getX(), y = pv.getY(), z = pv.getZ();
    IRenderTypeBuffer.Impl buffer = Minecraft.getInstance().getRenderTypeBuffers().getBufferSource();
    IVertexBuilder builder = buffer.getBuffer(RenderType.LINES);
    MatrixStack matrixStack = event.getMatrixStack();
    matrixStack.push();
    matrixStack.translate(-x, -y, -z);
		
    // disable depth here, somehow

    // for debugging: put wireframe around 0,0,0
    WorldRenderer.drawBoundingBox(matrixStack, builder, 0, 0, 0, 1, 1, 1, 1, 0, 0, 1);

    buffer.finish(RenderType.LINES);
    matrixStack.pop();
}

It appears that this requires both `RenderSystem.disableDepthTest()` and `RenderSystem.depthMask(false)`.
