I just have a quick question…I keep trying to do a test render using yafray. All I get is a black screen, and nothing…I even just made a small simple scene just a square and plane…I changed to Yafray and hit the xtml or whatever its called and still just a blank screen after 20 minutes and I finally just cancelled it. Does it have to do with my PC memory/Speed?
yafray can take a long time to render, but you should be able to see its progress in the command console. also remember that generally you will need to turn the lamp/lamps to a higher setting than you would with the internal raytracer.
And, instead of lamps (or rather together with lamps), you can use Global Illumination – when you switch to YafRay Renderer, you get two new tabs: YafRay and YafRay GI. In the second one change Method to Full and Quality to Low (or better if you have time:)).
Ok, I admit this is probably just a noob issue, but I’m having the same problem. I have Blender 2.36 and Yafray 0.0.7 (On Suse Linux 9.2 if that makes a difference)
I am trying to make a very simple test render just to see if everything is working, and all I get is a black render window. I too have left it go for a long time but nothing ever comes out.
I tried following the instructions above (about light intensities, global lighting, photon counts, etc), but none of the changes seem to make any difference.
Is there a sample blend file somewhere with an appropriate yafray setting so I can at least be sure my installation is setup right? Then I can go and look at all these settings in my test render knowing I at least have the basic configuration.
The black screen can be a result of many problems, first you must check if yafray dosent crash on your system, in most cases the whole blender will crash, if not then you might see some output in the’ terminal window’ that sprang up when blender was started.
As far as i remember suse9.2 installation of yafray worked fine for me.
If you do compile yafray then you must compile blender from the same machine to get them working fine. If you still have problems send me the sample blend fine and I will check if for you.
