hi @Cleverlike_Studios  
Working on a similar problem

[2024.10.18-02.34.52:241][0]LogShaderCompilers: Display: Compiling shader autogen file: C:/Users/jxxx/AppData/Local/UnrealEditorFortnite/Intermediate/ShaderAutogen/PCD3D\_SM5/AutogenShaderHeaders.ush  
The Shader settings are wrong yours is PCD3D\_SM6

First, try the easier shortcut to UEFN and add DX11 as an Additional Parameter

 ![UEFN-DX11-Shortcut](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/8/0/48025e1315b4b3e2c0c38a332bf923b731ed0f74.png)

in this picture, copy and paste the line below we need to add Dx11 and sm5  
to give -d3d11 -sm5 at the end of Target box

```auto
"C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\UnrealEditorFortnite-Win64-Shipping.exe" -d3d11 -sm5

```

Now start UEFN from the Desktop Shortcut

Update remove the highly technical text as of 32.00 the control file .ini no longer exista
