using whatever works best to my taste, I devise recipe as I cook
and in this case (top to bottom):
%
078 overlay
100 screen
100 soft light
100 normal
so that this simple cube-mapped mixture gives the appearance of clear volumetric depth, otherwise the blend was too soft, leaving a muddy & unclear aftertaste :p
no triplanar or randomization added :)
still need to test those noodles,
tnx for the heads up maru
