Nathan, I’ll defer to one of the more experienced developers, but I believe you still need to copy the channels (RGB? RGBA?, etc) from the selected input to the output in your _engine call, or nothing will be available downstream. It would be a pretty mindless copy, but it still needs be done, imho.
Steve From: [email protected] [mailto:[email protected]] On Behalf Of Nathan Rusch Sent: Thursday, May 12, 2011 11:53 AM To: Nuke-Dev Subject: [Nuke-dev] Simplest input switching implementation Hello all, I’m working on a plugin that does input switching based on some hash-related criteria, and I’m wondering what the most basic method of only passing through a single input would be (a la the Switch node). Right now I’m using a NoIop with my comparison code in _validate, and I’m wondering what steps I need to take to only pull data from one of my inputs. Right now I’ve pared it down to only call copy_info( i ), but even when I’m hard-coding in 1, it’s still returning the image data from input 0, so clearly I’m missing something mission-critical. Sorry for the basic question, but this has me pretty stumped, and I haven’t been able to dig up anything on the new mailing list forums.
