I'm currently running Houdini 16.5.268 in CentOS 7. I have Redshift 2.5.49 installed and Arnold as well. Currently, if I drop down a mantra node in even the simplest of scenes, I get a lot of strange Redshift messages in the terminal when I attempt to render. The renderview says Generating Scene; the scheduler says the mantra process is running. I get the following output in the console.

Is this some kind of weird configuration error? Anyone seen this? I can't render in Mantra at all.

Actually, I think it's not Redshift breaking anything. This has only happened since I installed Redshift but I was reading the logs incorrectly maybe. Arnold renders fine; Redshift renders fine; Mantra does not render at all, even when I remove Redshift and Arnold from my environment.

Actually I'm having a similar problem with the same log info but in windows, suddenly mantra stops rendering and display a redshift description error.

Anyone have any solution?
