there is another important button, it is located next to the button for calling the render settings. This is "Enable sky lighting". This button adds a cool blue light. In the third quality mode, this light simply colors the entire scene with cold light, no more. But in other modes (everything will continue) this light is of great importance. Notice how the time has increased. Strongly. But you have to pay for everything. Not much yet. But it should be continued..
