Hi there, my name's Trevor, I have just been following your 3d gems tut, but as someone else has commented, the controls don't appear to work properly. I am running Apo7x16.
I would love to finish mine, but as soon as i enter the Z controls it goes pear shaped! I have messed around and found setting to minus .06 is better but still not like yours, i can only get the sphere in the center to protrude. this happened with another 3d blooms tut as well
