Hi again,

I've come back to the problem that I had several days ago. According to the StructureBlockRenderer way of doing it, I have the above code. It sill doesn't render anything. Well, I suspect that it is rendering it, but in the wrong place. Am I linking the wrong buffers? Am I missing something important? Is my translation wrong? I haven't been able to understand exactly how the render process works, so, any explanation about it would be welcome.

Hope you can help me, this is the code:

 @SubscribeEvent
    public void onRenderLastEvent(RenderLevelLastEvent event) {
 	    
   		PoseStack pose = event.getPoseStack();
    	LocalPlayer player = Minecraft.getInstance().player;
    	VertexConsumer vc = Minecraft.getInstance().renderBuffers().bufferSource().getBuffer(RenderType.lines());
    	Camera cam = Minecraft.getInstance().gameRenderer.getMainCamera();
    	
    	Vec3 vec = player.getPosition(0);
   		Vec3 camvec = cam.getPosition();
    	
    	double px = vec.x;
    	double py = vec.y;
    	double pz = vec.z;
    	    	
    	double d0 = camvec.x;
    	double d1 = camvec.y;
    	double d2 = camvec.z;
    	
    	pose.pushPose();
    	pose.translate(px - d0, py - d1, -pz - d2);

    	LevelRenderer.renderLineBox(pose, vc, -5, -5, -5, 5, 5, 5, 0.9F, 0.9F, 0.9F, 1.0F, 0.5F, 0.5F, 0.5F);
    	pose.popPose();
    	
    }

I reply to myself. I finally got it:

@SubscribeEvent
    public static void onRenderLastEvent(RenderLevelLastEvent event) {	
		
		Minecraft mc = Minecraft.getInstance();
    	LocalPlayer player = mc.player;
    	Camera cam = mc.gameRenderer.getMainCamera();
    	LevelRenderer renderer = event.getLevelRenderer();
    	
    	PoseStack pose = event.getPoseStack();
    	MultiBufferSource.BufferSource buffer = mc.renderBuffers().bufferSource();
    	VertexConsumer vc = buffer.getBuffer(RenderType.lines());
    	
    	Vec3 vec = player.getEyePosition(event.getPartialTick());
    	double px = vec.x;
    	double py = vec.y;
    	double pz = vec.z;
    	
    	Vec3 camvec = cam.getPosition();
    	double d0 = camvec.x;
    	double d1 = camvec.y;
    	double d2 = camvec.z; 	
    	
    	
    	pose.translate(px-d0, py-d1, pz-d2);
    	LevelRenderer.renderLineBox(pose, vc, -5, -5, -5, 5, 5, 5, 0.9F, 0.9F, 0.9F, 1.0F, 0.5F, 0.5F, 0.5F);

    	renderer.renderLevel(pose, event.getPartialTick(), event.getStartNanos(), true, cam, mc.gameRenderer, 
    			new LightTexture(mc.gameRenderer, mc), event.getProjectionMatrix());
    }   

Just had to call renderLevel at the end of the event handler.

 Rendering the level solved the problem for me in 1.18.2

But it looks like it causes an infinite recursion in 1.19.
