I'm looking to make a driver that outputs a random value between a specific range (in this case -1 to 1) as a way to randomly change the factor value of the Simple Deform modifier. So that I can duplicate an object, and the factor is a random value, giving unique shapes for each, but within a range of acceptable values.
I've taken a look at other questions/answers, but I haven't found anything that pertains to my situation, or that I don't understand how it's being done.
I'm not looking for other workflows or other ways to go about what I'm doing with the modifiers. I'm specifically looking for a way to make a random driver that outputs numbers within a range. Nothing more. I'm not interested in animation nodes either, not at the moment anyway, so that's not an acceptable answer either.
I'm not wanting to sound rude or anything. Please just answer the question as it is in the topic.
