The problem isn’t hex vs. int; the value you’re getting back from the Python
knob is identical to the hex value returned by the nuke.tcl call. The issue
you’re running into is that the nuke.tcl call is returning the hex value as a
string, so you need to cast it to a numeric type before you can actually use it.
n = nuke.selectedNode()
tile_color = int(nuke.tcl('value [topnode %s].tile_color' % n.name()), 16)

Subject: Re: [Nuke-users] python [topnode] equivalent
Thanks Ivan.
This was pretty much exactly what I was looking for. However I had to change it
a little bit because this was returning the tile color hex value, if I
understand all this correctly, and my function needs just the integer value. As
I can't assign or set a tile_color using hex, or I haven't been able to figure
it out.
Anyways, for whatever reason this does the trick, kinda mixing your code with
what I had before. I am still not very sure why the tile_color has 2 different
value formats.
n = nuke.selectedNode()
topnode_name = nuke.tcl("full_name [topnode %s]" % n.name())
topnode = nuke.toNode(topnode_name)
tile_col = topnode['tile_color'].value()
Thanks again and much appreciated.

of the top node, you could of course do:
n = nuke.selectedNode()
tile_color = nuke.tcl("value [topnode %s].tile_color" % n.name())
Hope that helps

You can use nuke.tcl() within python to execute a tcl command.
So, in your case, something like this should work:
n = nuke.selectedNode()
topnode_name = nuke.tcl("full_name [topnode %s]" % n.name())
topnode = nuke.toNode(topnode_name)

Hopefully a quick question,
If I currently have a node selected somewhere in a tree, and I want to access
the topnodes tile color using python, how would I do so? Using
[[topnode].tile_color] doesn't seem to work as it is tcl? Looking around it
seems you need to check dependecies of all the nodes or something, but I
haven't been able to get anything to work. Is there no way to convert the tcl
function to work in python?
Thanks in advance for any help,
Adam
