[2.3] Overlays not rendering correctly

Post by psysu »

Ogre Version: 2.3.0
Operating System: Windows 10
Render System: Direct3D 11

Hi, im using testing text overlay element in a scene. its not rendering properly, like instead of captions i get white bars in its place and all of them are rendering in 3D.

like here :

here how i initialize overlay system and created overlay elements.

Setting up Overlay System:

Code: Select all

{
	/** 
	* Root instance creation and getting the RenderSystem through config dialog
	*/
	m_pOverlaySystem = OGRE_NEW Ogre::v1::OverlaySystem();
        m_upRoot->initialise( false, m_upWindow->GetWindowTitle() );

    CreateRenderWindow();
    SetupResources();
    LoadResources();
    CreateSceneManager();
    SetupOverlaySystem();
    CreateCamera();
    SetupCompositor();
}

void SetupOverlaySystem()
{
	m_pSceneManager->addRenderQueueListener(m_pOverlaySystem);
        m_pSceneManager->getRenderQueue()->setSortRenderQueue(
            Ogre::v1::OverlayManager::getSingleton().mDefaultRenderQueueId,
            Ogre::RenderQueue::StableSort
        );
}

Creating Overlay Elements:

Code: Select all

	auto* overlay_manager = v1::OverlayManager::getSingletonPtr();
        auto* overlay = overlay_manager->create("Test_Overlay");
        
auto* panel = static_cast<Ogre::v1::PanelOverlayElement*>( overlay_manager->createOverlayElement("Panel", "Test Panel") ); panel->setMetricsMode(Ogre::v1::GuiMetricsMode::GMM_RELATIVE); panel->setPosition(0.35, 0.2); panel->setDimensions( 0.35, 0.35 ); auto textarea_element = [&overlay_manager]( const std::string& instance_name, const sample::utils::vec2f& position, const float& char_height, const std::string& caption) -> Ogre::v1::TextAreaOverlayElement* { auto textarea = static_cast<Ogre::v1::TextAreaOverlayElement*>( overlay_manager->createOverlayElement("TextArea", instance_name) ); textarea->setMetricsMode(Ogre::v1::GuiMetricsMode::GMM_RELATIVE); const auto& [pos_x, pos_y] = position; textarea->setPosition( pos_x, pos_y ); textarea->setCharHeight(char_height); textarea->setFontName( "DebugFont" ); textarea->setCaption(caption); return textarea; }; auto caption_1 = "hello this is an text area element"; auto caption_2 = "This is to test multiple text area elements in a container"; auto char_height = 0.03f; auto textarea_1 = textarea_element( "DebugTextArea_1", {0.0, 0.0}, char_height, caption_1 ); auto textarea_2 = textarea_element( "DebugTextArea_2", {0.0, 0.2}, char_height, caption_2 ); panel->addChild(textarea_1); panel->addChild(textarea_2); overlay->add2D(panel); overlay->show();

Re: [2.3] Overlays not rendering correctly

Post by dark_sylinc »

Don't create m_pOverlaySystem before m_upRoot->initialise.
It needs to be done after the first m_upRoot->createRenderWindow call (see Samples/2.0/Common/src/GraphicsSystem.cpp).

As for the rest, I don't know what's the exact cause unless initialization order was the cause.
It sounds like the overlays are using Pbs materials instead of Unlit.

These errors:

Invalid parameter at line 418 (@foreach). 'first_valid_detail_map_nm' is not a number nor a variable
Invalid parameter at line 466 (@foreach). 'hlms_lights_directional' is not a number nor a variable
Invalid parameter at line 473 (@foreach). 'hlms_lights_directional_non_caster' is not a number nor a variable
Invalid parameter at line 481 (@foreach). 'hlms_lights_point' is not a number nor a variable

Are highly suspicious because they indicate an error in how your Hlms is setup, more specifically the Samples/Media/Hlms folder is being improperly loaded or has been corrupted with wrong files (e.g. left over from 2.2 installation?).

Update: Oh I also forgot. See if Colibri is a better fit for your needs. Overlays are no longer maintained and cause a few problems due to their v1 interface.

Found the Issue!!! while registering HlmsUnlit, instead of giving default paths of HlmsUnlit, i had given default paths of HlmsPbs. now the overlays are working properly
