<div>Hey Jens,</div>
<div> </div>
<div>thanks for your reply and your work. I've done a Windows 64bit build that can be downloaded here (thanks to Bastien for your advice!): <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>To the issue with SSS:</div>
<div>I've encountered a similar error but can't reproduce it. When using CUDA, I get the message that I'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. </div>
<div> </div>
<div>Maybe someone can figure out what's happening here. </div>

<div>Hi Pascal<br/>
<br/>
I made a Linux portable build ( all distro ) of cycles_disney_brdf<br/>
<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/>
