TheFixer - Yes, that's my problem too!

I would never describe the function editor as being intuitive to use - which is why I've, so far, avoided using it. This Terrain plugin seems considerably easier to use for creating ripples, wakes, etc. round objects in water.

TheFixer and I and a few others contributed to a thread a few weeks back when we discussed various work-arounds such as creating small rippled terrains in Vue to place round objects, etc. I guess without knowledge of the function editior we'll have to stick to these, somewhat, long-winded solutions!

Any good tutorials on how to do ripples, etc. in the funstion editor greatfully welcome!
