A TLDR for those who just want it short and simple, Raytracing and bakes do similar jobs but do it separately, Raytracing is done dynamically by well, raytracing (duh), Baked lights are quite literally just a texture, Thats it. Its just a texture that you can specify the size of that stores lighting information baked in the editor which if i remember right is raytraced information. You dont bake raytracing, thats not how it works, you bake baked lighting only, its in the name.

Well, here’s the thing though, raytracing can be used to bake lighting as well, it’s just a matter of whether it is stored to lightmaps or if it’s updated every frame. In the future, there will be an update to UE4 that takes advantage of raytracing cards to speed up light baking.
