Sharpen

Lite-C:

Material and function to adjust the effect:

//Sharpen
MATERIAL* Sharpen_mat =
{
	effect = "sharpen.fx";
}

function Sharpen_set_Value(strength)
{
	Sharpen_mat.skill1 = floatv(strength);	// should be higher than one. Looks good between 10 and 50
}

The sharpen.fx file:

//////////////////////////////////////////////////////
