So I am by any means an expert on these subjects so sorry if asking noob questions I am still learning. I know most of these things can probably be found in the documentation online but it is extensive and quite frankly thanks to me still being new I do not even know where to start in the do cumentation.
So my question is this:
(1) I can not seem to build lighting anymore in my scene. I have enabled Lumen and it seems to be related with that. Some posts mention disabling the option “force no precomputed lightning” but I am not sure I want that based on my assumption that Lumen fundamentally renders scenes differently from the pre-lumen scenes.
(2) I am not sure how Lumen interact with stationary/static/moveable lights. When I make the lights static the preview word becomes visible in the casted shadows/light. Previously I needed to build lighting for that to disapear, but since that option is now gone I am unsure how to proceed. Should I just make all lights stationary?
(3) Another problem seems to be related to viewport clipping or something LOD. When I approach my lights the intensity seems to jump down (decrease) at a certain distance and when I move the camera back the light intensity (for the lack of a better word) seems to jump back up. See my attached image for clarification of this issue. This problem especially seems buggy but I am unsure where to start troubleshooting.
Some information that might be valuable.

-
- Dynamic Global Illumination Method = Lumen
-
- Reflections Method = Lumen
-
- Use Hardware Ray Tracing when available = active
