Now that I'm in front of Nuke I realize that I've missed the brackets on
the return code in order to allow it to be evaluated by the label.
So here is the actual code:
[if {[value this.disable]=="false"} {return "[knob this.tile_color
0xff000000]"} {return "[knob this.tile_color 0xff00ff]"}]
Hope it helps.
cheers,
diogo
