In this example renderLayerNode is inside of foo's scope so you can
not use that variable outside of it unless it is a global. I dont use
pymel, I use Maya Python and it would look like this:
def foo():
global renderLayerNode
global scpt
renderLayerNode = "foo"
renderLayerNodeB = "foobar"
scpt = 'print renderLayerNode'
scptB = 'print renderLayerNodeB'
foo()
# this works
exec( scpt, globals() )
# this will fail
exec( scptB, globals() )
What does the scpt variable string look like? What scope is it being
called from? Are you calling variables from other scopes that are not
global?
