YafRay render (Black screen of death)

[Wetwat]

I'm new to blender and I'm having some problems getting the internal Yafray render to work. When I first opened blender I was able to just click the use Yafray button in the render menu but now when I try to render scenes with it all I get in a black render. Could someone give me a step by step run down of what I need to do to fix this. If it's a lighting thing then how and what must I set up first. I've looked everywhere for a tutorial on this problem and can't seem to find one. I must be the only dummy out here that can't figure it out

Any help would be great,

ok this is probably to simplistic, but try cranking up your lights

for example if you have a light in blender set to 1.0 / crank it up to 3 or 4

just my 2 cents

Well I'll give it a try but I doubt it.
Thanks though-

It's really really black!

Some more information, like errors in console window, might be useful.

Check:

- YafRay is correctly installed? Open a terminal and type yafray -v.

- YafRay is crashing? Check console (in Blender) and read the messages...

I've got blender version 2.36 now and still have the same problem. Do I need to download yafray and install it somewhere? I was under the impression that yafray was part of the new blender releases?
Also why would the Yafray render work in one .blend file and not all the other ones? Same light sources and still nothing.

Where is the console you guys are refering to?

[Samjh]

The Blender console. When you start Blender, two windows should open -- the Blender console and the Blender workspace itself.

I haven't used Blender on a Mac, but it should be there.

I'm not an Mac user, but I think that Mac users have to do something else for showing console window.

Hey guys thanks for the help. I found the problem! Under the Yafray settings the xml option was turned on so I guess it was exporting the dang things to some folder on my hard drive. I tured it off and it worked like a charm. . . well now I just need to figure out how to speed up the render time without scrificing quality.

-This site is great

I'm not an Mac user, but I think that Mac users have to do something else for showing console window.

FYI - Mac users can get access to the Console for processing and error messages by starting the Blender App from the Console ("Terminal" or "XTerm" applications) command line. The easiest way is to cd to the Blender application's directory, for example:

% cd /Users/[username]/blender/blender.app/Contents/MacOS/

(where [username] is your "home" directory - your path may vary - the "%" here just represents the Unix prompt - do not type it). Remember that "blender.app" on the Mac is not the application, but a folder that contains a bunch of things, including the application ("blender") and a lot of Python scripts (in the /.blender/scripts/ directory)!

Then you can launch Blender at the command line:

% ./blender

THe Blender app will start up as if you double-clicked it, but you will be able to watch what is going on "behind the scenes" in the Terminal or XTerm window that lauched the app. You may have to resize the Blender window to fit the screen - you can do this in the "Window" OSX menu bar - drop down and select "Zoom".

To avoid doing this "cd" drill every time, you can write a short AppleScript that automates the command line instruction and make it a little desktop application (or place it in the Dock). Then, a double-click on the script's icon will open Terminal, launch Blender and, away you go! The AppleScript command to tell the application Terminal to run a command line string of text is "do script". This is the text from the Terminal dictionary:
---
do script: Run a UNIX shell script or command
do script plain text -- data to be passed to the Terminal application as the command line
[with command plain text] -- data to be passed to the Terminal application as the command line, deprecated, use direct parameter
[in reference] -- the window in which to execute the command
--

So you would write a short script in the ScriptEditor window like:

tell Application "Terminal"
do script ./Users/[username]/blender/blender.app/Contents/MacOS/blender
end tell

Have fun,

You know, it's much easier to just use the 'Console' program in the Applications/Utilities folder, which just displays the console output in a window. No command line required.

But that's no fun!

Are you using photon lights because Yafray sometimes doesnt "like" them.
Try A different type of light.

Hi Darkhorse, wellcome to the forum.
