This version uses Arnold 4.2.10.0

Enhancements

  • Up to 40% faster export of polygon meshes.
  • EXR append mode now works properly.
  • Improved OpenVDB plugin and shaders.

Linux installation notes

  • Starting from SItoA 3.6.0  (which uses Arnold 4.2.6.0), the minimum requirements for Linux have been raised to the equivalent of RHEL/CentOS 6 for glibc and libstdc++. However, Softimage ships with a legacy libstdc++ that is put in the LD_LIBRARY_PATH and that hijacks the system one, making it impossible to load the Arnold DSO. To fix this, one solution is to preload the system libstdc++ before launching Softimage:

     

    export LD_PRELOAD=/usr/lib64/libstdc++.so.6

     

    Another solution is to remove the libstdc++ from the Softimage install and let the system one take over, for example:
    cd my_softimage_install/Application/bin
    mv libstdc++.so.6 libstdc++.so.6.bak
    mv libstdc++.so.6.0.10 libstdc++.so.6.0.10.bak
