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! alt text! ---

I updated the BP like in the attached image. It still doesn’t work and produces errors while playing in VR ![344091-error.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/f/e/4/fe4a4ec5517c1e156c2698d2b79064238800abb4.jpeg) ---

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?
