Different rendering processes within unity as mods and alternatives to U3d Pipeline

Hi "Les Unity Dune Mercenaries "

Can you please recommend a bunch of rendering platforms that change or tweak the U3D totally using ray tracing, bloom, to have an effect a bit more like sunflow and blender ray tracing view. It's fine if there is a crazy performance impact, i'm on the lookout for old codes which changed the way the light and the atmosphere is generated from A-Z in unity...

I need very good metal, with imaginary reflects, slightly shiny transparent shaders, plastic and subsurface style things, whatever you can offer i am interested, especially if i can just load it and it completely changes the fast game shaders to a higher level of something crazy.

Thanks!
