we use the following libs for LuxCore

edit OIIO is now 1.8.13 and OpenEXR/IlmBase 2.4.1

It will be hard to reproduce the crash on Mojave and up since we (LuxCore) do not have an AppleDeveloperLicense .. yet .. so the .zip is not signed or notarized. So on Mojave and up SIP must be disabled otherwise it won’t work at all. So High Sierra is needed to reproduce the bug without SIP problems.

Thanks for all your work !!!

Installing and activating the add-on I get:

Library not loaded: @loader_path/libOpenImagedenoise.1.1.0.dylib

And indeed I can't find that library in the .zip. We may be able to hide to more symbols to fix this, but it's hard to do blindly so it would help to have that file.

I'm not sure why LuxCore must be signed to work, we actually configure the Blender signing/notarization to allow loading unsigned shared libraries (com.apple.security.cs.disable-library-validation).

Oh the lib update messed up azure .. Thanks for the hint and sorry for the inconvenience.

I uploaded a current version i just compiled on High Sierra.
and tested on 2.81a(works) and current git (crash as described above).

BlendLuxCore

About the signing part ...
I compiled yesterday on Mojave and didn't get around SIP.
local and free dev signing didn't work for pyluxcore.so. -> crash
I got a report with SIP protection protecting me... when i disable SIP it works without problems. Help here would be wonderfull.

Thanks for your help !
