Re: [Maya-Python] attributeAffects and input output name?

[Michael Boon]

The compute function won't be run until you ask Maya for outputB, right? 
Changing the inputs just flags the output as dirty, and then accessing the 
output causes the calculation to be done.

I can’t tell for sure, not without an example of sorts, but it looks like
you’ve got the answer in the question. attributeAffects is how you tell
Maya which attribute should trigger your compute function. What have you
tried so far, and what happens? What did you expect to have happen?
