I really love blender... mainly because it's free, but anyway it is a great program.
I think it would be the best to make a new button "rendering with external renderer", where you can chose the options for the raytracing-process (dof, photons, everything and what about real motion blur?) and then blender automatically exoprts all the information dircetly to an external renderer; why not yafray....... This wouldn't just be good for blender it would give blender a BIG BIG BIG step forward. Now, blender is a very good modellingtool and also animationtool, as far as I can tell... But the renderer is old, lets face it... And unfortunatly no exportscript works well on my system, so I'm stuck to the internal renderer and I can't use any of my graphics or animations in videos.
It's not important which raytracer will be used for this, it is important there IS a raytracer implementet into blender.
And just think of it: with a more or less powerfull raytracer (also working on animations) blender would be a real option besides commercial products!
I want to appologize for everything, you have heard already and I wrote again, but i wanted to tell you my opinion and well, you've read it. thanks!
No, yafray developpement is still active.
I downloaded YAFRAY and it produced some very nice results. I might start using it instead of the internal Blender one!
Hopefully it can be integrated into Blender.
