dynamic day night cycles can’t be done with stationary or baked data. ofc not. you have static data. if you want dynamic you gotta use movable lights and deal with the computation load. it’s not easy but can be done. you have various limitations, like light counts per mesh or shadow performance. you gotta optimize the hell out of it. the only thing that you can bake is ambient occlusion, since it is always the same no matter the light condition. it’s tricky. yes.
