- I thought of one small twist to this method: Using Surface Morph and a
- repeating envelope, why not have each ripple area morph back to the larger
- puddle surface in between ripples? That way the ripple areas don't stand out
- when they are quiet. Or, greatly exaggerate the ripple depth and then only
- morph 50% into it. That way, you get droplet ripples and overall puddle
- ripples both at the same time. I haven't tried it but it sounds good on phospor.
-
- Hope I didn't come off sounding like a jerk, Mark. If it hadn't been for
- your idea, I would never have thought of this one.
