Pc game using mobile renderer?

How do I package a desktop game using the mobile renderer for play on a stand-alone PC?

Surely this is a setting somewhere?

Last time I saw you needed to modify the engine source a little bit to include the mobile preview shaders in PC packages. That’s how they did it in Disc Jam: How Disc Jam Reached 60 fps on Intel Processor Graphics using Unreal Engine 4 - Unreal Engine

Hi Manoel but how exactly is this done?

Having a look at:

And being awfully scared of amending code that might cause things to go pop permanently.

Can someone please explain to a numpty like me:

Can I just load a map using the mobile renderer without streaming the level? how would I hook up the custom “IsInMobilePreview” node to event begin play?

How do I create the “IsInMobilePreview” function, create function then just drop in the code?

Additionally in my version of ue4.15 I already have an “OpenGL ES3.1 Experimental” option in project settings >> platforms >> Windows >> Targeted RHIs, should i still amend “GenericWindowsTargetPlatform.h” and “WindowsTargetSettingsDetails.cpp” and “WindowsD3D11Device.cpp”?

In any case where are these files located?
