Frost

Lite-C:

Material and function to adjust the effect:

//Frost
BMAP* Noise1_bmap = "noise1.jpg";
MATERIAL* Frost_mat =
{
	skin1 = Noise1_bmap;
	effect = "frost_fast.fx";
}

function Frost_set_Value(xOffset,yOffset,Frequenz)
{
	Frost_mat.skill1 = floatv(xOffset);	//has to be very small at about 0.005
	Frost_mat.skill2 = floatv(yOffset); //you should usually use the same value here
	Frost_mat.skill3 = floatv(Frequenz);	//try something between 0.1 and 1 here
}
