What you want to do first is to click on Gradient Intensity and select a number. Then turn Turbo Mode on. After that gradually adjust you number as preferred. ( Click the Green Flag after every adjustment ). Once that is done, turn Turbo Mode off and stop the project. Click the green flag and re-run it. Leave it for an hour or two ( The smaller the number, the longer the developing time ) to develop. Come back later to view your wheel. Do NOT turn Turbo Mode on to develop your wheel ; it ruins the product! Yes, I know it is slow, but good things come to those who wait. 20, 30, 40, 45, 60, 80 ,90, and 180 are good round numbers to experiment with.
