When the group is exported as a gizmo, it can be saved locally where only you can see it or it can be saved in a central directory where everyone can see it. You'll need to check with your IT guy where the public directory is, because it's different at each facility. So let's start by seeing how to save this group out as a gizmo. The first thing you want to do is set the sliders for the default value you want when the gizmo is opened. Let's say I want the scale to be .8 and I'm fine with the blur size being 0. So I'm going to save out MyGizmo locally.
We do that by switching to the node tab and right down here, Export as gizmo, click on that. So I'm doing this on a Mac and for a Mac, the location to save it is your home directory, in the .nuke folder, and then you give it your name, MyGizmo, no extension. When it's saved out, the .gizmo extension will be added. The important thing is it goes into the .nuke folder, under your home directory. Click Save.
If you're on a Linux machine, the .nuke directory is also under your home directory. For Windows XP, it's the C:\Documents and Settings\your login name\.nuke. Okay, we've exported the group as a Gizmo, but it hasn't shown up yet. By clicking the Node Graph and do a Tab key to search for it for MyGizmo, I don't find it. The first thing we have to do is restart Nuke. When Nuke starts up, it searches all the path names and makes a list of all the gizmos and all the plug-ins.
So I'm going to go ahead and restart Nuke. Okay, so I've restarted Nuke, and I've brought in my same purple face read node, and I have no gizmos. Even though I've restarted Nuke, if I hit the Tab key and do a search on MyGizmo, I don't find it. What I have to do is we go to the Miscellaneous folder and select All Plug-ins > Update. Now with the Tab key search, I type n My, and I see MyGizmo. There it is. I hook it in here.
You'll notice it opened with a scale value set .8 which was my default, and the blur size of 0. So don't forget, wherever the sliders are set when you export the group as a gizmo, that will become the default setting when you open that gizmo. Gizmos are quick and easy to create and are a very slick way to add new nodes to your Nuke library.
