Hi all, I'm using mantra to do IP rendering. When i select the area to render, nothing happens. Usually spits out an error message with this :

Could not open the script or pipe
Could not write to the script or pipe
Failed to complete render Manra1

Any ideas??

This is a common error if you have your mantra rop incorrectly set up.
Check it out slowly once again, if your object, camera and light scope shows existing objects, if output and shadowmaps and whatever are set to correct paths, all sort of things.
Make it as simple as you can.
If you end up hopeless, sure of your innocence, restart houdini and reload the scene, it helped me once.

This occurs often and usually is caused by a basic human error.

Yeah, that usually means you don't have a valid Camera specified…

I think that might be the problem. I'll give it a whirl and let you know what happens. Thanks!
