Self-imposed limits, such as rules, tools or formats, that shape a work. The Oulipo writers made them a method.
I've purposely chosen my tools to avoid those situations. There are trade offs, of course. It's not like I can easily produce the same pristine results you could quickly get with Houdini or Autodesk Maya. But these constraints are my way of maintaining my little, self-contained world of how I make art.
