So if you want to change the dials on things, you have to click the green flag afterward. Some things look weird if you turn the dial too much but honestly it doesn't change much. Refresh it if you don't like the results. RECOMMENDATION!!! USE THE RANDOMIZER (DICE ICON) FOR BETTER RESULTS!
Again, borrowed some code from another project but this was about a year ago and I don't remember which one it was so forgive me.
