ISymbols Not Attaching to Entities (Unigine 2.9.0.2)

[robert.walters]

I have no trouble creating a head's up display by attaching a plane to the default view but when I try to attach planes to entities I can't seem to ever see the symbols.

 

	//In AppSystemLogic.h
	IG::ISymbolsController* myController;
	IG::ISymbolCircle *hoop;
	IG::ISymbolsPlane *plane;
	IG::ISymbolText *alt_baro_text;

	//In AppSystemLogic.cpp
	IG::ISymbolsController *myController = ig_manager->getSymbolsController();
	myController->clear();
	IG::ISymbolsPlane *plane = myController->createPlane(0, ig_manager->getView(0)); //this one works fine
	plane->setScreenSize(1920.0f, 1080.0f, 64.0f, 59.5f);
	RenderState *render_state = RenderState::get();
	int halfHeight = render_state->getHeight() / 2;
	int halfWidth = render_state->getWidth() / 2;
	plane->setUVSize(-halfWidth, -halfHeight, halfWidth, halfHeight);
	//set plane properties
	float near = ig_manager->getView(0)->getNear();
	float far = ig_manager->getView(0)->getFar();
	float top = ig_manager->getView(0)->getTopDeg();
	float aspectRatio = float(halfWidth) / float(halfHeight);
	//add text symbol to screen, this displays fine
	alt_baro_text = dynamic_cast<IG::ISymbolText *>(myController->createSymbol(IG::ISymbolsController::SYMBOL_TYPE::TEXT, 0));
	plane->addSymbol(alt_baro_text); // add symbol to plane
	
//This one doesn't work
			ig_manager->getSymbolsController()->createPlane(1, ig_manager->getEntity(0));//never see the result, I have also tried other entities with no luck
			ig_manager->getSymbolsController()->getPlane(1)->setScreenSize(1920.0f, 1080.0f, 64.0f, 59.5f);
			ig_manager->getSymbolsController()->getPlane(1)->setUVSize(-halfWidth, -halfHeight, halfWidth, halfHeight);
			ig_manager->getSymbolsController()->getPlane(1)->setPhysicalSize(7, 7);
			ig_manager->getSymbolsController()->getPlane(1)->setBillboard(1, 1);

			 
			IG::ISymbolCircle *hoop = dynamic_cast<IG::ISymbolCircle *>(ig_manager->getSymbolsController()->createSymbol(IG::ISymbolsController::SYMBOL_TYPE::CIRCLE, 322));
			ig_manager->getSymbolsController()->getPlane(1)->addSymbol(hoop);
			//setting position does not seem to make any difference, still can't see it
			ig_manager->getSymbolsController()->getPlane(1)->setPosition(vec3(16.383f, -1.0f, 1.0f));
			hoop->setCenter(0.0f, 0.0f);
			hoop->setRadius(3.0f);
			hoop->setInnerRadius(1.0f);
			hoop->setFill(1);
			hoop->setColor(brightRed);
			//if I add hoop to plane 0 it appears as expected

Hi! 

i just resized the circle

hoop->setRadius(300);
hoop->setInnerRadius(100);

size 3 is very small, because halfWidth and halfHeight are very large (413 * 806 for me)
