Just the scale of the waves is weird. I am setting skill44 in the script to 1, I tested it in shadertest.c and it looked good. But if I set it like this or in WED the shader just is flat, no single ripple. I set it to 50,50,50,1 (skill1 - 4) like in WED and in script with skill41 - skill44 but nothing... I hope that I can find it out myself
