Rendering Techniques

Hello guys, I am making a large scene in UE and I want to optimize it in terms of performance. Does anyone know where I can find the algorithms/shaders for rendering techniques such as LODs, hardware tesselation, view frustum culling?Books or websites? I don’t want to use material editor for these techniques, as I want to get deeply.

You’re describing the main point of Unreal and it’s unlikely you’ll be able to optimize their internal pipeline (since you need references)

Check Epic Games and do a search for optimizing. There’s quite a bit you can do to optimize Unreal based on settings and choices of the models and materials.
