Hi J-S, Although not an optimal solution, and probably more of a work-around to your question ... I use a skydome as well. In my case, I just create a sphere whose radius is that (or a little less than that) of the camera's far-field value, which I've set to be quite large (60,000-meters). This works for my use case. But again, it's not an optimal solution. I'd also be interested in a more optimal and scalable solution.
