Properly set COUNT_3

Indeed, I was always setting COUNT_3 to 0.

This new patch should solve the issue (at least if it's related to tex clause
size). I can't test on Unigine because Unigine doesn't want to start anymore
since I updated my fedora beta, however oversatured hue in some Lightmark scene
is gone.
