Agreed, one of the things I would like to see in dynamic lighting is some kind of improvement of shadow cascades to make the transition between baked and dynamic light more seamless, this is especially true on characters shadows and especially true when you are using longer lenses in the game which would force you to calibrate the cascade distances at a more precise and sensitive numbers, but when you move said camera then the whole thing needs to be re-calibrated again (non 3rd person cameras more 3d platformers or fixed camera workflow) and current;y there is no way to adjust the cascades through blueprints or other more accessible ways).
Other annoying issues revolve around the SSS behaviour, and lack of SSS back scattering for skin, proper IK and so on… (this is just me repeating myself).
In any case this is just one of those threads unfortunately.
