I have suddenly started seeing the sea as a brightly coloured mosaic, how do I reset please?

[Lill Chaffe]

I know this is me being dumb but I can not figure it out so any advice or help would be wonderful...

I have a little sl house on the mainland looking at the sea.  In the past it always looked like water and just this week it turned to a bright changing slightly trippy mosaic of technicolour.  Everything else in sl looks normal. 

Please can anyone advise which of the many setting might help me turn it back to water looking please?

Thank you

 

 

thank you Vanilla and Lindal, you were both right it was the way to fix it.  It turned out it had changed itself when I was playing with makeup appliers on a mesh head.  I never even thought makeup would change the sea; SL is magical!  Thank you so much for helping me : )

Could it be you have, by accident, changed your Windlight Settings and changed the water setting?

Vanilla's suggested the most likely answer.  For more on windlight, see: http://acrossthegridwithlindal.blogspot.com/2014/02/sidereal-sun-time-in-second-life.html
