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.
Typing in "False" makes the object visible and typing in "True" hides the object.
intfor boolean drivers .. eg
1 if var > 39.9 else 0will set the driver to
Trueif some driver variable is greater than
FalseEditing the scripted expression to be either
Falseisn't really the concept behind drivers. $\endgroup$
