hi all
i was very pleased when i saw that yafray supports subdiv surfaces.
some quick tests and i wanted to get some better Gi result but the rendertimes are high even with 2 cpus. manly i use from time to time tempest with pixels 3d which is know for slow speed but it looks like even they are faster than yafray when you want good illumination and good soft shadows.
how is your experience? i even launched carrara 2.0 and the GI there is a lot quicker.
am i doing something wrong???

I use 2 CPU’s for rendering too in Yafray. I render multiple 3d characters in scenes with buildings, etc. I have poly counts of 30,000 up to 250,000 plus in a scene. I mainly rely on scanline renders for most of my stuff. But in Yafray these renders can take a very long time to compute. Other renderers like Carrara handle the polys in a scene faster. I am sure that the Yafray team is working hard to speed up the Yafray renderer. For Yafray to be used for complex animation like the Blender renderer, speed improvement is a must. All of this these Blender and Yafray features are still in the early stages of development so we have to give it time.
I used Yafray before it was linked from inside of Blender. It was a chore to manually set up uv textures for a render. Now all I have to do is hit the render button and render my pre-uvmapped scenes in Yafray. That’s some major progress. So I’m willing to wait for further improvements.
Blend on!
yafray has a lot of “loading overhead” in addition to plain olde rendering.
I did not say I stop refusing using it right now!
I was just wondering if the speed is my result
or just Yafray´s normal speed.
When I saw this caustic rendering on their website
I thought the speed was incridible.

2 shadowmap lights , resolutions : 200 and 100
Photonlight 1: 50000 photons
Polygon count: 1170, Render samples: 6
Memory used: about 6 Mb, Machine: Athlon 1GHz 512 ram
Render time : 1m 14s

I second that.
My notebook has similar specs, but rendering far less complicated images costs a lot more time (maybe 6 times as much), I can’t even get those results with my 2Ghz Desktop PC.
Is that the usual Linux speed improvement???
That picture was done with the normal photonlight and the shadowmapped ‘softlight’, you only see caustics, no GI, so it is very fast to compute, might actually be faster now, that was one of the first pictures created with one the earliest versions of yafray more than a year ago.
But of course there is always room for improvement.
ah there is no GI!
because of this picture with caustics i always though that yafray must be
fast as light! sad its not this way but as you said it is a R&D.

Yes for the moment , Yafray is still slow when it comes to complicated scenes. But the fact that it is integrated with Blender might be a good hope for supporting development both from coders and users.
Also it’s a bad idea to compare with Carrara, as it is one of the fastest hybrid solution on the market, with Cinema4D, and of course Electric Image 
if you start to compare with Mental Ray Final Gathering, or Lightscape, the fact that Yafray is slow becomes very relative
well as i stated out i dont complain and i know that most times comercial engiens are a bit more advanced because of R&D funds.
commen sense.
I know that carrara is quit fast. the modeler is bad but the engine isn´t to bad.
i was just so amazed when i saw that caustic image and asked myself how i can do it in blender.
i hope that the speed will be increased and i think that since yafray is integrated and already famous that this will help as well.
one big plus is that dual cpu is supported!!!
