Hello together I'm having problems with calling camera->SetMultisampleMode on a leadwerks C++ project - the game just crashes. Here's what I've tried so far: - Creating the camera from C++ - Using the camera created by the map - Turning on and off different post-effects applied to the camera - Calling camera->SetMultisampleMode(16) - Crashes - Calling camera->SetMultisampleMode(8) - Crashes - Calling camera->SetMultisampleMode(4) - Does not crash! - Calling camera->SetMultisampleMode(32) - Crashes - Starting the executable from the editor - Starting the executable from visual studio - Starting the executable by simply double-clicking - Checking the documentation over and over again - Google - Asking on the Forums (this thread) - Removing all post processing effects - Calling camera->SetMultisampleMode(24) - Crashes Visual Studio throws me out at context->Sync(false) in App::Loop. The error reported is a read access violation at 0x0000003C and the exit code is 0xc000013a. The crashes really only occur when I set the multisample mode. The Camera is created normally via Camera::Create. After that I fetch two pivots from the loaded map and position the camera at one and have it look at the other, and then some other stuff: if (camera) { camera->Move(CamPivot->GetPosition()); camera->Point(CamDirectionPivot); camera->SetMultisampleMode(16); world->SetLightQuality(3); if (camera->AddPostEffect(AssetPath::getPostEffect("08_PP_bloom+godrays.lua")) == -1) { System::Print(">>>>>>>>>>> Unable to load BLOOM and GODRAY Shaders: " + AssetPath::getPostEffect("08_PP_bloom+godrays.lua")); }; if (camera->AddPostEffect(AssetPath::getPostEffect("99_pp_fxaa.shader")) == -1) { System::Print(">>>>>>>>>>> Unable to load FXAA Shaders: " + AssetPath::getPostEffect("99_pp_fxaa.shader")); }; if (camera->AddPostEffect(AssetPath::getPostEffect("ssao.lua")) == -1) { System::Print(">>>>>>>>>>> Unable to load SSAO Shaders: " + AssetPath::getPostEffect("ssao.lua")); }; } After that nothing happens, except for sound loading and calling SetMousePosition. Nothing great happens in App::Loop either - freelookmode is removed altogether. Am I doing something completely wrong here? Thanks in advance for any help! EDIT: Might be worth mentioning...
