heyas;

 

   i've been using snarlygribbly's wonderful ezskin 2, not enough to be more than a newbie with it...  but in my last scene, i used the special effect  "very wet skin high bump."  it looked great with my preview renders to the scene window, but when i changed the render to 1600x2600, some of the water drops picked up a red tint.  (the tint is more blackish if i dont use sss to render.)

   i'm using the 'office stairway' HDR light set, to give a blue tone to the scene.  i have blue-tiled walls, and white, grey, and slightly bluish light.  i thought maybe there was something whacky with the reflections, so i added the EnvSphre to the scene, but that didn't change anything.

 

   does anybody know why the water drops are changing colour?  and how to fix it?
