From the documentation: “It’s possible to manually change rotational values of the Directional Light in the SunSky Actor. However, when you change other settings that affect other parts of the SunSky Actor, your manually adjusted rotational values will be reset to the default position. This prevents contradicting values incorporated with the idea of a geolocated calculation.”
Are you trying to use the geolocation features or do you just need a sun light?
I’m farily new to unreal engine, I’ve been trying to use it importing my work from sketchup with the datasmith, I’m doing architectural not trying to make a game. I cannot find any way to chance the sun direction of the sunsky: rotating the object does’t do anything (and there is no refresh botton, that I saw some older version had it), changing the parameters of the rotation changes themporarely the light, but as soon as I release the mouse button the light goes back to the original state. It’s pretty annoying, not sure if it’s a bug or what.
