blender crashes when I use yafaray

[joshp1]

I don't know if this is a blender problem or a yafaray problem because this is the only engine that it does it to. When I select yafaray blender crashes, sometimes. Other times when I do a render. I've checked the console and no errors. I was just wondering if anyone could help

joshp1, your not alone!

I've installed Blender (2.72) on an USB-Drive ... on one computer (Windows 7 x64) Yafaray works on the other one (Windows 8.1 x64) it does not!
All I get is this ntdll.dll error, which I can not fix. Very annoying.

Hi, I'm also having the same problem. I just installed yafaray a while ago and when I render the scene I get the "Blender stopped working" message. Running Blender 2.72.

maybe this could work

I wish :-\
Tried different things, even downloading and replacing the local ntdll.dll ... only that windows 8.1 refused to boot for a few times and tried a repair some files - fail! Somehow I'm back ... still don't know the entire damage from this little excursion.

Funny thing is, I tried it on virtualbox on windows 7, Yafaray works. I ran Blender from the same directory on virtualbox as with windows 8.1.

Summary: I can't replace the ntdll.dll without bricking my pc - without replacing ntdll.dll, Yafaray won't work :-[

The same problem for me too. Installed Blender 2.72 on a pc with Windows 8.1 64bit (fresh installed OS) and than installed the Yafaray 0.1.5 addon in Blender.

When I try to render a scene with Yafaray -> "Blender stopped working"
When I simply go to the material screen (while having Yafaray selected as render) -> "Blender stopped working"

But actually I have no ntdll.dll error...

Any ideas what could cause such a problem? Must have something to do with Win8.1 64 bit, because I have no problems with Win7 64bit and Blender 2.72/Yafaray 0.1.5

I would be really glad if that could be solved somehow Thanks!

I suspect it is the material preview windows producing issues which is calling a yafaray rendering event. That could be the reason it crashes either when you launch render or when you go to the materials panels. Also we somewhat need more diversity of builds, done with different compilers on different systems etc.

[schnellchecker]

Is there some kind of logging-mode in blender? If so, I can log you what happens in python while doing the rendering (crashing^^).

I use Blender 2.72 with Yafaray 0.1.5 on all my systems (2x Win8.1 64bit and 1x Win7 64bit) and the combination only works with Win7.

What else can I do to help?

Hi,

I just discover that when isolating the plugins folder from the bin\plugin, yafaray works normally except that no material preview, no render image since
the plugin library of dlls is isolated.

I suspect that crashes for win 8, using Blender 2.71 or higher version is caused by the plugin dlls not compatible with Win 8 drivers or it has something to do with python 3.4
or maybe since if all the plugin dlls are compiled using mingw which may not be compatible with Win 8.

Attached is my test. I manage to run yafaray in Blender 2.71, 2.72, 2.73 but without crashing Blender but no plugin folder.

These may be a clue to developers and I hope it helps pin down the culprit of the crashes somehow.

Please try this build:

Thank You!
Works with Windows 8.1 x64 and Blender 2.73!

Hi David,

This really works!
Thanks for the build.....I have tested in Win 8.1 Blender 2.73 64 bit.
32 bit build is working good as well...

[David Bluecame]

Thank you, guys, I'm glad that it works for you.

I've made two new "Beta 2" for 64bit and 32bit. The only change is that you don't need to copy the two DLLs to the main Blender folder. These will likely become the next official builds for Yafaray, so if you also want to test them (just in case there is some new issue, although I think not) they are in:

If you use "beta2" then you can delete the files libstdc++-6.dll and libwinpthread-1.dll from the main Blender folder that were needed by beta1. Please let us know if these beta2 versions still work fine for you.

Thanks and best regards!

sorry about taking so long to reply but thank you David Bluecame that worked.
