Update time on sun and sky actor

Hi all, I have placed a Skysun actor in my scene.

I have 2 arrow actors in my level and on hover I will update the suntime.
I have setup a level BP, but it isn’t working right now…
I want to set dynamically the suntime between 6 and 12, and back when hovering the other arrow.

What did I do wrong?
Thanks in advance!

I updated the BP like in the attached image.

It still doesn’t work and produces errors while playing in VR

I checked a youtube video to do so, but see in my project that I have a SunSky actor (with the lights and environment in it) but the BP sun position is only the star-shape and no lights. I guess that’s the reason it won’t work and spits out all the errors?

How can I change the suntimes in the sunsky actor?

I did some things wrong and reset it up. It doesn’t give me the errors anymore. Now it’s partially working. Feeding the solar time with increments of -0,1 and 0,1 works, but way to fast. It flips through the sunpositions in just 2 seconds.

Also, I have to put my laserbeam long at an arrow to make it happen. Just for about 12 seconds and the the sun positioning starts happening (too fast indeed).

I guess I have to set an initial solartime at begin play and have to tweak the settings of increments…
But how can I setup this the best way?
