Ok, I might come after the war is won .. (or lost) but since I'm new in using CFX, I tried a lot of stuff recently. I came across those 2 findings:
1. in colors.txt -> look that your tridentm=0000 if your'e not using a trident configuration.
Don't know exactly why but each time I accidentally set it to something else, my FoC stays steady whatever param I set.
2. for some color settings I use for fcolor, same stuff, FoC effects are ignored or really tamed however color and fcolor are quite different.
Again, don't ask me why but changing slightly one of the di(c)e color settings of fcolor solved the problem.
