Can't reproduce it yet in simple example since it tends to happen with big maps with many entities. In my game it can be reproduced by: 1. New game or Choose Map ->Easy Map -> Ok 2. F5 to quick save 3. After a second (have a delay to prevent other issue with double click) press F9 for quick load. 4, Do Quick Load 5+ times and eventually it either HUD became invisible fully or partly (buttons still can be pressed so it's not sudden UI->SetHidden anywhere) or game stuckes on Loading screen, but in fact game is just not being rendered - "Error: Invalid value" in console after every world->Render() Another way is starting new game, returning to main menu and starting again. Also beside HUD also anything transparent seems to be non rendered - shotgun cones, fog cubes, blood decals. And for some reason gibs invisible too (they only thing with a physics tho).

Look at 123 line loadingWorld->Render(framebuffer); I was doing similar thing to show loading screen when main menu was loading #include "UltraEngine.h" #include "ComponentSystem.h" using namespace UltraEngine;

Default start map from template Happens after first enter press: Comment in loop "world = CreateWorld();" to get another render crash (RecordDraw) but it's not consistent and may take several attempts (Andy have this issue i believe): #include "UltraEngine.h" #include "ComponentSystem.h" using namespace UltraEngine; int main(int argc, const char* argv[]) { RegisterComponents(); auto fiplugin = LoadPlugin("Plugins/FITextureLoader"); auto displays = GetDisplays(); auto window = CreateWindow("Ultra Engine", 0, 0, 1280 * displays[0]->scale, 720 * displays[0]->scale, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); auto framebuffer = CreateFramebuffer(window); auto world = CreateWorld(); WString mapname = "Maps/start.ultra"; auto scene = LoadMap(world, mapname); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { if (window->KeyDown(KEY_ENTER)) { world = CreateWorld(); scene = LoadMap(world, mapname); } world->Update(); world->Render(framebuffer); } return 0; }

Hello Basically I want to draw have an image in the scene behind everything, but I need to have wireframe enabled. So I cant just place a face with a texture and put it behind. The skybox is also rendered in wireframe mode. So I need to have an Image Drawn before everything renders but this is impossible because I believe every pixel has a color value to it which renders over the drawn image. I also saw a thread (I think in c++) before about a similar problem from about 2014, and it said that there could be a feature for this implemented soon. So is there a feature for this ? Or a workaround ? In this photoshopped picture you can see that Leadwerks is visible but behind everything.

So they released an update for the amd graphics bug. But I loaded up my leadwerks and updated my project but it is stll happening. Am I missing something? please help

I'm trying to get a 3D character to display on top of the screen as part of the HUD (so unaffected by anything in the scene as if it's it's own scene). How could I achieve this effect?
