i made a linux build with the latest svn and when i render is all black and the script crashs when i select my camera.

does anybody has yaf(a)ray working with the blender svn?

now the script doesn't crash but i get this error when i render:

Have you installed and used the Yaf(a)ray exporter script?

It looks like you just didn't select the lamp and material types.

For that you must open up the script, and while you have the lightsource to configure selected, go to the "lamps" tab.. Then choose a fitting light type from the list..

in the "materials" tab you can select all created materials from a list..

Everythjng else looks just about right...

Another update:

http://lynx.aspect-design.de/yafray/bf- ... yafa187.7z
http://lynx.aspect-design.de/yafray/yaf ... _setup.exe

Again svn trunk (rev. 12265 or so), although currently i'm really not sure how stable that is, maybe i'll do a 2.45 too...

Path tracing has been updated with new caustic settings, also photon mapping has some missing stuff added, but still missing some bits for absorption, am still designing better volumetric handling...

And of course fixed several bugs i found on the way, cleaned up console output a bit etc...
Think i'm finally close to where i wanted to be for calling it an initial release.

Oh, the sunsky stuff has not been added yet, i noticed there needs to be done a bit more to make it as complete as it should be, sorry...
basically there is missing a whole lot of code to compute the proper sun color as implemented by the original authors...

-edit-
oh and some platform maintainers would still be highly appreciated...

Can anybody give us normal - step-by step instructions for downloading (what and where) instaling and setting up yaf(a)ray for Linux?

Lynx! It looks like the new release has one serious bug - the UV Mode is gone! We've got the rest (Edit Mode, Object Mode etc) but the one mentioned above simply disappeared!

hi lynx..


1. is there plan to implement the traceable option lile in blender?..This is useful to make materials insensitive GI and shadows like glass windows.
The render time will decrease a lot in many scenes.


2.Is there a way to make meshlights invisible?


3. Is there plan to implement the other texture projections than Plane and UV? Like the Cube Projetion or Refl Map Imput..

*lol* the new UV editing is the best thing that has been done to blender's UI lately in my opinion ;)

"traceable" makes little sense, since yafray is a pure raytracer, the object would simply be gone. So no, i don't plan this.
For the glass shadow problem, there's the fake shadow option now.

mesh lights cannot be invisible.

cube mapping perhaps, but the other input types behind orco violate the concepts of yaf(a)ray.

I second that request!
I think someone made a script that downloads the code and compiles it - it's in the yafaray tests thread somewhere near the end... I don't know if it works with the new version though. I'm trying it now...

How to get the sources is described in the >>wiki<<...the sources also contain information in the "INSTALL" file.

For every halfway decent Linux distribution, everything should be available with a few clicks (or commands) in the package manager...
Tools you need: subversion, g++, scons
Libraries you should have: zlib, openexr, libjpeg, libpng, libxml2, freetype2, of course with development files (naming of those packages depend on distribution, it's like "libxml2-dev" on ubuntu), and you'll probably be prompted to install additional dependencies (like "gcc-base" or "python2.5" or something, if it's not installed yet)

That's all there is, get sources, change into checked out dir and type "scons" to compile, "sudo scons install" to install, and make sure you have ldconfig setup properly (also explained in the >>wiki<<)
