Hi,

I’m looking to be able to change the position of the sun through the Sky Atmosphere Actor at run time. I don’t want to use the BP Sun Position Calculator because I want the physically based sky actor aka the Sky Atmosphere. I see that the FastSkyViewLUT holds a latitude/longitude texture ray marching array but I’m not sure how to get that? I want to be able to change the position of the sun through blueprints at run time to match the latitude/longitude coordinates I have. Thanks for any help!
