4.15.1 ResizeCubemapArrayGPU Crash


Updating my game to 4.15.1 fixed the ResizeCubemapArrayGPU crash for the vast majority of users, however we still have reports trickling in from folks about this crash, so I don’t think UE-42165 is fully fixed:

Insulam-Win32-Shipping.exe!FReflectionEnvironmentSceneData::ResizeCubemapArrayGPU(unsigned int,int) C++
Insulam-Win32-Shipping.exe!TGraphTask<class FScene::AllocateReflectionCaptures(class TArray<class UReflectionCaptureComponent *,class FDefaultAllocator> const &)'::28’::EURCMacro_GPUResizeArrayCommand>::ExecuteTask(class TArray<class FBaseGraphTask *,class FDefaultAllocator> &,enum ENamedThreads::Type) C++
Insulam-Win32-Shipping.exe!FNamedTaskThread::ProcessTasksNamedThread(int,bool) C++
Insulam-Win32-Shipping.exe!FNamedTaskThread::ProcessTasksUntilQuit(int) C++
Insulam-Win32-Shipping.exe!RenderingThreadMain(class FEvent *) C++
Insulam-Win32-Shipping.exe!FRenderingThread::Run(void) C++
Insulam-Win32-Shipping.exe!FRunnableThreadWin::Run(void) C++
Insulam-Win32-Shipping.exe!FRunnableThreadWin::GuardedRun(void) C++
Insulam-Win32-Shipping.exe!FRunnableThreadWin::_ThreadProc(void *) C++

If it helps, the game utilises level streaming heavily, and it seems to only happen at the time levels are streamed in and out. This crash occurred far more frequently before the 4.15.1 hotfix, however folks are still reporting it after the upgrade.



Hey AlanEdwardes-

We have received other reports of this occurring in 4.15.1 and have pushed the fix to 4.15.2. The public tracker has been updated to reflect this.


Hi ,

Fantastic news, thanks for getting back to me. We’ll update once the hotfix is live.
