Why doesn't Sun Brightness get set properly?

Hi, appologies straight away, if this is in the wrong section ( this is my First question in Here) . Just started learning Blueprint programming from tutorials.
Basically, I made a simple landscape on a new map, with skysphere - at the moment, I made a simple Blueprint, shown below:

IsFPressed is a boolean, that toggles, when Button F is Pressed/ Released.
SunShine is just a float I made, that would change by 1.25, and the Sun Brightness should read off it.
As you can see , I made the EventTick constantly “update” the skysphere’s Sun Brightness based on SunShine var, but when I run the simulation , pressing F does nothing- the sun doesn’t become bigger/ brighter, like it should, when I do it via details tab in level editor.
Any ideas?

Hi, thanks for reply, but this simulation showed, that Numbers for Sun Brightness DO Change (when I choose he skysphere during simulation, in Details tab), it’s just the actual ingame brightness that doesn’t seem to update?! not sure why

In BP_SkySphere it changes Brightness inside construction script only and not inside UpdateSunDirection. You need to fire something like this i believe.

Hi, again, thanks for the Reply
Where exactly do I include that node? (which BP)
Also, I’m not sure I got BP_Good_Sky_Sphere anywhere 0_o

Works for me

Please don’t forget to mark my answer as accepted if i was able to help you)

about That “BP_” bit- I managed to find Just Sky_Sphere (reference), but I couldn’t get it to work- it still doesnt get any brighter ((
the Numbers DO Change for sun brightness- as before, but the simulation doesnt show it for some reason - as if it needs to be Updated or Something.
