tl;dr: <\/strong>Batch convert your favourite Nuke Gizmos into “Grizmos”.<\/p>\n<\/div><\/div>\n

Hi folks,<\/div>\n
\u00a0
<\/div><\/div>\n
So here I have a new little Python script for those who find a little boring\u00a0<\/strong>converting Gizmos into “Grizmos” manually.<\/strong>\u00a0Just in case, I\u00b4ll remind you that one of the best ways to make sure all your fancy Gizmos are going to render in the farm, or that a user that does not have a particular Gizmo can still open a comp that has it and work on it, is simply converting that Gizmo into a Group, thus getting the so-called\u00a0 “Grizmo” (as Hugo L\u00e9v\u00e9ille would call\u00b4em).<\/div>\n
<\/div><\/div>\n
<\/div>\n
What this script does, in its first version, is basically creating a Grizmo per each Gizmo found in a passed directory. AKA a batch Gizmo-to-Group converter, or a batch\u00a0Grizmo\u00a0Creator… And only for Windows users, at the moment.<\/div>\n
<\/div><\/div>\n
<\/div>\n
How to use it?<\/strong><\/div>\n
<\/div><\/div>\n
<\/div>\n
1 – Store and name the Python script<\/strong>\u00a0in a folder that Nuke is going to look at when it comes to importing Python scripts. Try the command “print nuke.pluginPath()<\/span>” in the script editor if you are not sure where your Nuke installation is looking for Plugins, Python Scripts and such.<\/div>\n
2 – Import the script<\/strong> you have just saved from Nuke\u00b4s script editor like “import module_name<\/span>“.<\/div>\n
3 – Call the main()<\/span> \u00a0function<\/strong> from the imported script like “module_name.main()<\/span>“.<\/div>\n
4 – If everything goes ok, you should immediately see a pop-up window asking for you to select the “Gizmos Path” directory. Navigate to the folder<\/strong> where you store all your fancy Gizmos and click ok.<\/div>\n
5 – Now you should have as many <\/strong>Grizmos as Gizmos<\/strong> you had in the former directory, with the “_grizmed” extension added to the original name. For instance:<\/div>\n
\u00a0 \u00a0 – Cryptomatte.gizmo (original Gizmo)<\/div>\n
\u00a0 \u00a0 – Cryptomatte_grizmed.gizmo (Grizmed\u00a0Gizmo)<\/div>\n
6 – Enjoy<\/strong> your brand new fancy Grizmos :D<\/div>\n<\/div>\n

important<\/strong>: If you find this usefull, it\u00b4s always better to create a Nuke menu from where to call the function.<\/p>\n<\/div>\n
