I thought I would like to very gently raise a subtle issue, which is where is luxrender going.
I have heard a lot of comments that luxrender development is slowing down or stagnating yet at the same time luxrender is being again and again recognized as one of the leaders in photo-real CG.
Are we too going to be poisoned by the growth metric which has trashed so much of the world?
Speaking as a artist I have almost everything I want from luxrender, I could use the current dev version for 10 years and still not be finished with the art I have in mind. I could use blender 2.49 in conjunction with this and never miss anything, the only reason I am switching to 2.6x is because I am to lazy to maintain the 2.49 exporter myself.
This is a complex issue relating to insecurity and the shinny factor but what does it have to do with art? Also, what does popularity have to do with interest in the technology?
When you work on the luxrender code base are you doing it because you are interested in the math or because you want to be rewarded with recognition and validation?
I don't see anything wrong with slowing down and just enjoying working on beautiful stuff.
With Cycles being in the main blender "trunk" I think we need to ask ourselves why are we doing this? Are the interest based values good enough or do we want to be recognized as being elite? I found the response to the SIGGRAPH thread very positive in that no one wants to go and talk about SPPM. To me this is almost Zen and like drinking clean water because it does suggest that the interest based value system is still intact.
So I close with the question, why is luxrender dev "slowing down" bad or even a valid idea?
Personally I am sick of this endless growth/popularity metric, lets think about doing art for a while.
