Hi,
I am working on an image which needs lots of waterdrops on a label. I do not succeed in making the water drops lighter than the surface on which they sit, normally a water drop catches light, and focuses it onto the surface, so that it appears brighter. see example on the cyan background.
I tried all kinds of Nd values, from 1.1 to 1.8, with no result about brightness change. only a bright rim appears with the higher ND values.
the attenuation is set to 10 times the size of a drop, so that is ok, and the transmittance is set to 255 white.
the shape of the drop is a perfect half sphere.
I tried placing the drops a fraction above the surface of the label, and also intersecting the label. the latter gave worse results.
is there a way I can make these drops brighter?
tnx
wim
