Hi

For all kind of sunsky backgrounds and even for gradient background, calculating the correct horizon line height would be a great addition, not only for compositing purposes, but also when we need to directly visualise this horizon line in our renders or into reflections. The idea is that the more height, the lower the horizon line. The feauture could be implemented with just a parameter that ask uses to introduce a "Height" for the background, which in fact would account for the viewer's height, then it would lower the horizon line as this height increases, as per the reference below:
