well… once i did Shift+Mouse1 (select the whole brush)+ set the texture … then after i made the shader i made ctrl + shift + mouse1 (select the surface) + shift+a and put that sp_mediumwater on it (it had been nodrawwater before)…
then my shader got corrected here and without changing the textures they are displayed transparent in radiant and NOW even in game… but it is SOLID+
EDIT: SOLVED
