I have been working with a lake with 4 surface layers.
base color is dark grey.
surface layer 1 is lighter grey.
surface layer 2 is white, very high elevation. > 3500
Surface layer 3 is lighter green near tree level. 3100 > 3500
Surface layer 4 is dark green elevation lower elevation. < 3100
lake at 3207, water level 3625 (? not sure what this is really doing with water level, my camera is at 3215)
With surface layer 4 off, everthing works great.
Turning on Surface layer 4, the reflected images on the lake are green.
I have attached two images for examples
thanks
