Hi, I'm trying to setup a switch that turns on and off depending on the value of a shell environment variable.
I can access the variable using getenv or $env, but I'm not sure how to evaluate strings in Nuke's expressions. For instance, if I want to evaluate in a switch node if the current user name is "xavierb", I expected one of these to work: $env(USER) == "xavierb" ? 0 : 1 [getenv USER] == "xavierb" ? 0 : 1 In both cases I get an error. How can you evaluate strings inside Nuke nodes? Thanks for any tips! --Xavier
