those lights are going to have to be moveable; static lights only bake light maps. there’s nothing preventing you from using static/stationary lights for stationary light sources (that’s the intent) and a dynamic light for the sun. you won’t (afaik) be calculating light maps for any objects beyond the radius of a static/stationary light so there shouldn’t be any performance issues there. i did a quick google search and it doesn’t look like there’s anyway to disable light maps on an object but still use that object in lightmap baking, if that’s what you’re trying to do.
