[MtoA] Is there an ARNOLD_PROCEDURAL_PATH environment variable?

No, there isn’t. HtoA recently added support for an ARNOLD_PROCEDURAL_PATH environment variable, but neither MtoA or Arnold itself support ARNOLD_PROCEDURAL_PATH.

Here’s a few things you can do:

  • If you’re kicking ASS files, you can set the procedural search path on the kick command line. For example, assuming ARNOLD_PROCEDURAL_PATH is set in your environment, you could do this on Windows:
       kick -set options.procedural_search_path %ARNOLD_PROCEDURAL_PATH%

    Or this on Linux or OSX:

       kick -set options.procedural_search_path $ARNOLD_PROCEDURAL_PATH
  • You could add the procedural search path to the system path (PATH on Windows, LD_LIBRARY_PATH on Linux, DYLD_LIBRARY_PATH on OSX). Arnold will then find the procedural by searching through the system path.
  • Maya, you can put an environment variable in the Procedural Search Path text box. Note that you have to use square brackets, like this: [ARNOLD_PROCEDURAL_PATH].
