Hi,
I can reproduce this bug frequently.
I’m using Unreal 14.4.2 compiled from sources. I have GTX 460.
In attach the stack which ends with :
UE4Editor-D3D11RHI.dll!FD3D11Viewport::PresentChecked(int SyncInterval) Line 267
In attach you can see the log with -d3ddebug
The operations I do:
- I press F5 to launch debug of my project in Visual Studio
- I navigate to Content/ThirdPerson/Blueprints/ThirdPersonCharacter (which is BluePrintClass)
- I open it
- In the Class Defaults window I go under Mesh / Skeletal Mesh, and change the ThirdPersonSkeletalMesh with my mesh: kran_baserig_1_4
- I see the thumbnail getting updated and I see my char there, then black screen for 2 seconds, then the crash pop-up. NVidia tray icon is telling me the device stopped working. I’m using drivers 376.33
The project contains some proprietary art, but I can share it with you under NDA if you think it may be useful.
I can reproduce this 100% of the time (also after full PC restart).
I also have other crashes ending with D3D11Util.cpp Line 176
