I have a driver which toggles the visibility of a mesh. If I set the driver the scripted expression and type in "True" when the visibility is off, the visibility turns on. If the visibility is already on and I type in "False", the visibility does not change.

  • $\begingroup$ Useint for boolean drivers .. eg 1 if var > 39.9 else 0 will set the driver to True if some driver variable is greater than 39.9 else False Editing the scripted expression to be either True or False isn't really the concept behind drivers. $\endgroup$

  • $\begingroup$ I was using inequalities for my driver, but for simplicity, I changed the values to True and False while testing whether or not the driver works the way I thought it would. $\endgroup$

Typing in "False" makes the object visible and typing in "True" hides the object.
