hi im new to unreal engine. unreal 5.1.1 works great on my laptop until last week and after that this error apears when i try to open a project or even when i try to make a blank project and i cant do anything. i almost try anything (upgrading nvidia driver, windows, directx…) but nothing works… please please help me to solve this.
You need to change the Base system on startup then
go
notepad C:\Program Files\Epic Games\UE_5.1\Engine\Config\BaseEngine.ini
Control+F find “WindowsTargetSettings” at line 2874
Save the file on closing notepad and restart UE Editor.
You system now uses DefaultGraphicsRHI_DX11
in Project Properties go Platforms, go to Windows select Default RHI to be DirectX11 from DirectX12 and click ok to save
It suggests to do the following.
switch to SM6 to solve the problem—go to Project Settings → Platforms → Windows → D3D12 Targeted Shader Format → SM6
Hey i found a solution to this as just switching to direct x 11 in project settings. not sure why thats the issue but it fixed the crashing in blueprints window
hi @LordAzad
You need to make changes by going to you project root
Go to directory
C:\Users\Owner\Documents\Unreal Projects\MyProject2\Config
where Owner is your Username
In there right click DefaultEngine.ini
set the text to
[/Script/WindowsTargetPlatform.WindowsTargetSettings] DefaultGraphicsRHI=DefaultGraphicsRHI_DX11
-D3D12TargetedShaderFormats=PCD3D_SM5
+D3D12TargetedShaderFormats=PCD3D_SM6
-D3D11TargetedShaderFormats=PCD3D_SM5
+D3D11TargetedShaderFormats=PCD3D_SM5
Change the
DefaultGraphicsRHI_DX12
to
DefaultGraphicsRHI_DX11
Save and exit the file
Reload the project and hopefully it works with DirectX11 drivers
