Changing Light Temperature using a Slider

Hi , Im trying to make a slider with which i can control light temperatures of multiple lights , so that i can place them outside a window to alter between day light and night light

do i do this in a new blueprint?

Up to you. Not sure how the project you’ve got works. This was done in the Level Blueprint.

Im sorry for being such a dumbo , but how do i create that OnValueChanged_Event_0

When i tried to put this in the level blueprint , im getting these errors

Copy pasted a variable? Instead, promote it by right clicking the Return Value pin:

And use Assign:

To make life easier.

The Slider shows up when i start but its not changing the temperature , does it have to do anything that im doing this in lumen?

Probably. This is just a generic method of pushing data across. Never worked with lumen.

if i change the lighting to raytracing , will it work ? cause i just changed it in the project settings but it still doesnt seem to work , Ive also changed the lights from static to Movable , do i have to build the lighting or something?

Lumen also does seem to support , editable lighting , Im adding a link for reference below

Can you show the script, just to check things look ok.

Hello, can it be done to a blueprint actor wish controls all spotlights in the scene?

@RolandNakhoul Is this still related to the PM from earlier on?

Or is this a delayed first forum post? Or a new query?

Delayed post i guess, but related because first i created a blueprint to control all spotlights in my level but didnt manage to control its variables from the slider, that why i did it the second way ( the one you helped me with)
