Dunno what type of stuff you're trying to do, but I've found that vue treats lights pretty much as in the real world. So if you look on the web for studio lighting tips, if that is the sort of thing you're doing, then a lot of the examples they show can easily be adapted into vue. Also I have seen recomendations for the book 'Digital lighting and rendering' and whilst I've not got it myself, it is on my 'to get' list. Hope some of that helps
