Btw, this is an "Asking for render time" topic, I see that a lot of example renders on that could have used some help in rendering. This is expected, since not many of us have enough resources (or the patience) to render this amount of scenes. Check this one for instance:http://www.luxrender.net/wiki/Gold_material
And also, I guess new examples are going to appear soon in here: http://www.luxrender.net/wiki/New_in_1.0
So, I would like everyone to know I'm here to help when anyone is up to something new. Just ask!
