Increase Non-Streaming Texture Pool Size?

I’m struggling with some basics, but the solution described here seems relevant, thanks for confirming. In play mode a red warning comes up, “Texture Streaming Pool over 170 mb”, I assume my default is set to 1000, needs to be increased to 4000 mb, yes?

I lack the foundation to know just how this works, thanks for some explicit steps. I found and opened into Notepad DefaultEngine.ini, but I don’t see within it [/Script/Engine.RendererSettings]. The closest thing is [/Script/EngineSettings.GameMapsSettings]. Thanks for clarifying where the cursor goes, what code is dropped in, and if I simply save the file to have it called up within that engine build.

Many thanks.
