Hi Bill,
The dot node will take a tile color however, I've only been able to
successfully set an expression to the tile_color via python -- not to say it
isn't possible via tcl, I'm just not sure how.
When setting an expression via python 2 things happen:
1. The dot node gets the green "e" badge showing there is an expression
attached -- that may not be an issue for you.
2. The dot node then links a green expression arrow to the node directly above
it -- yes, you can turn these off, so again, it may not be an issue.
* I'm not aware of a way to turn off node badges and expression arrows on a
case-by-case basis -- that would be cool...
I may have achieved what you are looking for with the following function and
callback -- note: it's assuming your dot node is named "_dot_".
def dotTopColor():
d=nuke.toNode('_dot_')
d['tile_color'].setExpression('[value [topnode].tile_color]')
nuke.addUpdateUI(dotTopColor)
Hope this helps...
Cheers,
