you got me, I'm smarter than that, I was fishing and caught a bite

whoa both my fav water ppl in one day.

this is Cousin Ricky absorption, as they all have been
but now with the HF from TgQ


little too busy, perhaps windy, previous images were using TgQ norms

using norms it seemed water needed to at least touch the tile.
using HF I had a dark wall if not overlapping

one more correction, replace PX in the previous with:

#declare PX=pigment{  //Tile pattern x plane
      gradient x
      pigment_map{

        [  DimU/2 gradient y colour_map{[DimV/2 GrtCol][DimV/2 TilCol][1-DimV/2

        [1-DimU/2 GrtCol]
      }
      scale <TilSiz.u/BSiz.z/4,TilSiz.v/BSiz.y/3>

The busyness appears to be coming from refraction of the tile pattern.

Yes, make sure the water is *slightly* larger than the pool hole to avoid
coincident surfaces.

Any way you could render this first image at a higher resolution? I think I
might send it to my mother for her desktop background.

Well thanks...

As long as it all works out for you and we both learned something.  I always
take these things as a challenge to teach myself how to do something and
hopefully learn something.
