# fz_shdr_cbak_trns_avg

Description

Transparency shader average transparency function (Optional). This function is called by formZ at certain intervals, to determine an average transparency for this Transparency shader.
A typical implementation of this function would take all the individual transparencies used in the shader and calculate the mathematical average; for example : (trn1 + trn2 + trn3) / 3.0.
if this function is not supplied, the average transparency for a shader is always set to 0% (fully opaque).
