CinnamonMetal Posted March 1, 2018 Share Posted March 1, 2018 When creating Houdini path variables, is it safe to assume; if I create a variable `patha` with a value of `/1`. Then when typing `patha` it will automatically search the directory of 1 if I understood correctly ? Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted March 1, 2018 Share Posted March 1, 2018 Houdini uses environment variables in a Unix like way and if the environment variable is set before launching Houdini then it'll use it. See the documentation on it if you haven't already. http://www.sidefx.com/docs/houdini/basics/config_env.html The short answer is yes, if you define PATHA variable as "/1" then any time you use $PATHA it'll get replaced with "/1" in the text. Beware using variables that look like $PATH because that's a critical system wide environment variable. Ideally it would be something not close at all to existing variable names to avoid any confusion. https://en.wikipedia.org/wiki/PATH_(variable) 1 Quote Link to comment Share on other sites More sharing options...
