<div>Hey Jens,</div>

<div>&nbsp;</div>

<div>thanks for your reply and your work. I&#39;ve done a Windows 64bit build that can be downloaded here (thanks to Bastien for your advice!):&nbsp;<a class="moz-txt-link-freetext" href="https://www.dropbox.com/s/rkpbwr18dwptarr/blender_cycles_disney_brdf_win64_latest.zip?dl=1" target="_blank">https://www.dropbox.com/s/rkpbwr18dwptarr/blender_cycles_disney_brdf_win64_latest.zip?dl=1</a></div>

<div>&nbsp;</div>

<div>To the issue with SSS:</div>

<div>I&#39;ve encountered a similar error but can&#39;t reproduce it. When using CUDA, I get the message that I&#39;m out of memory but I also get this error when using the default SSS shader. On the CPU it once crashed with an EXCEPTION_ACCESS_VIOLATION. But since then no more crashes happened. I have also tested it with a new scene and with all other parameters on and off.&nbsp;</div>

<div>&nbsp;</div>

<div>Maybe someone can figure out what&#39;s happening here.&nbsp;</div>

<div>Hi Pascal<br/>
<br/>
I made a Linux portable build ( all distro ) of cycles_disney_brdf<br/>
<br/>
-- PACKAGE-INFORMATION --<br/>
Branch: cycles_disney_brdf<br/>
Revision: dbad91c<br/>
Submodules: locale 4c06104 addons 2155eb5 addons_contrib 98f1144<br/>
OS: GNU/Linux, Architecture: x86_64, GLIBC: 2.19<br/>
Builddate: Mi 20. Jul 11:46:49 UTC 2016<br/>
Filesize: 72398292 byte<br/>
Shasum: 5d535d7b5b6f12a6bf86c021fc530233586a1b0d<br/>

<br/>
Initial testing works so far, but there is an issue in SSS:<br/>
<br/>
In cuda:<br/>
CUDA error: Illegal address in cuCtxSynchronize()<br/>
<br/>
In CPU also just getting a segfault ( non debug build for now )<br/>
<br/>
Cheers ... Jens<br/>
