So I'm making pretty good progress with my little project so far, but there is one thing that gives me a headache and no guide so far could explain this to me.

I'm hoping you guys could enlighten me...

So from what I understand, when placing lights the most important difference is if it casts shadows or not.

Mos tlights that dont cast shadows will have the "NS" suffix in it's name, for example:

DefaultTorch01 => Cast shadows

DefaultTorch01NS => No shadows

So here are the problems I hope you could help me with / explain to me:

1. All the shadow variants not are always a LOT less bright than the NS counterparts. I couldn't find any explanation for it. ALL the data is the same except for the shadow part. Is that a bug? Can it be solved? Workaround?

2. The shadows come from completly illogical angles.

here is an example:

tree is on the left and light on the right side of the street. but the tree casts his shadows from left to right.... I'm guessing it is the moonlight?

In this case it's an omnidirectional light, Hemisphere does the same bug, haven't tried spotlight...

3. From what I understand there is a limit on how many shadow casting light can be placed before the Toolset decides it is to much and doesnt show them ingame or bugs them (flickering).

Most guides say its 4 light per cell. It seems that's not entirely true though since even if I have only 1 Light in my whole map, that still gets bugged sometimes, showing a red lightbulb in the CK and not getting displayed in game.

Soo..... what are the rules to placing shadow casting lights??

4. Lastly, Light in the creation kit:

For some reason the CK doesnt display light if I enable the Sky or the working Lights (Shortcut "A")

only if I disable both, the CK will show me lights on the map.

I'm not talking about the map markers, but the lights illumination effect.

Hope you guys can help me !

For shadow lights, you can only place them in interior cells, they won't render in exterior cells. Furthermore, only 4 can be rendered at a time, so this means you have to limit yourself to only using 4 per cell, or use room portals, to stop the lights from rendering when you can't see them.
