This version uses Arnold


  • Faster export times overall on Windows (up to 20% faster).
  • Faster export of polygon meshes (up to 35% faster).
  • Much faster export of ICE instances (up to 5x faster) and ICE cylinders, discs, cones, boxes (up to 3x faster).
  • Faster rendering when using SItoA shaders on Windows (up to 15% faster).

Linux installation notes

  • Starting from SItoA 3.6.0  (which uses Arnold, 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
