How to update variables (i.e. time, clouds, rain, fog) with respective slider (UE 5.3)

Hello everyone,

I urgently need help to understand how the sliders in a widget blueprint can be linked to individual variables of certain actors.

Specifically, I would like to be able to change the weather in my game with sliders.

To do this, I want to be able to adjust the time (SunSky), cloud density (VolumetricClouds), rain and fog (ExponentialHeightFog).

Let’s start with the cloud density. I have created a variable “DensityOffset” in m_SimpleVolumetricClouds_Inst for this purpose.
Now I want to be able to control this variable with a slider in the Blueprint widget in the range 0 - 1. Can you please help me with this?

The slider works for changing the time of day with SunSky, but there is also the blueprint function “Update Sun”, which is missing for the other variables, so what can I use instead of “Update CloudDensity / Update Rain / Update Fog” for my variables in the slider?

My working Blueprint to Update SunSky:

Thank you very much in advance :slight_smile:
