Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

DK2 VR Preview error

I'm getting a UE4 crash when trying to do a VR Preview and from the crash log it looks like it's referencing the D: drive but i don't have a D: drive on my computer. I have the latest firmware and sdk version and all of that, i also tested the DK2 in other apps and it still works fine.

This is the error log:

Unknown exception - code 00000001 (first/second chance not available) "Assertion failed: ViewFamily.RenderTarget->GetRenderTargetTexture() [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Plugins\Runtime\OculusRift\Source\OculusRift\Private UE4Editor_Core!FDebug::AssertFailed() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\core\private\misc\outputdevice.cpp:355] UE4Editor_OculusRift!OculusRift::FViewExtension::PreRenderViewFamily_RenderThread() UE4Editor_Renderer!RenderViewFamily_RenderThread() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\renderer\private\scenerendering.cpp:1328] UE4Editor_Renderer!TGraphTask<`FRendererModule::BeginRenderingViewFamily'::`17'::EURCMacro_FDrawSceneCommand>::ExecuteTask() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\core\public\async\taskgraphinterfaces.h:753] UE4Editor_Core!FTaskThread::ProcessTasks() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\core\private\async\taskgraph.cpp:430] UE4Editor_Core!FTaskThread::ProcessTasksUntilQuit() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\core\private\async\taskgraph.cpp:273] UE4Editor_RenderCore!RenderingThreadMain() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\rendercore\private\renderingthread.cpp:284] UE4Editor_RenderCore!FRenderingThread::Run() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\rendercore\private\renderingthread.cpp:385] UE4Editor_Core!FRunnableThreadWin::Run() [d:\buildfarm\buildmachine_++depot+ue4-releases+4.8\engine\source\runtime\core\private\windows\windowsrunnablethread.cpp:73]

I am having this problem as well. UE4 crashes every time when I am trying perform "VR preview" with DK2 connected. Did you get this solved CharlestonS ?

Nope, no resolution yet but i have a feeling it's a UE4 bug on certain systems and we will have to wait for Epic to address it.
