the channel Hotbox

i wrote this small tool in PySide for easy and fast changing channels/layer inside the viewer since the dropdown menu or the page up/down solution are too tedious. after i tested it a while in production i added the option to also use it for shuffling out channels.

it is based on the current viewer and which node it is connected to. NOT the selected node inside the nodegraph. the script checks all available layer at this node and gives you the option to show, shuffle or grade them.

demo on vimeo

click:
change the viewer to the selected channel

shift+click:
shuffle out all selected channels

strg+click:
create grade node with channel set to selected

alt:
switch viewer back to rgba

To install with hotkey on alt+q, add this to your menu.py and make sure that the script is located in your nuke plugin path:

import channel_hotbox
nuke.menu('Nuke').findItem('Edit').addCommand('HotBox', 'channel_hotbox.start()', 'alt+q')

I have worked with it under windows and linux. on ubuntu it seems correct, under centos is an issue with the transparent background, which will shown as black.

Any kind feedback is welcome.

cheers,

Falk
