I've noticed in Unity 5 that the Preview pane doesn't appear to have any lighting (other than very dark ambient light). In Unity 4 there always seemed to be a fixed directional light associated with the Preview as there was a nice "bright spot". Does anyone know if this is configurable in any way? It's not something that I've ever stumbled across if it is. I used to use the renders in the Preview pane to create item icons (example below), but can't do that now.
