Shake Tips 006_normal pass control math!

first create two local value: 經度"longitude" and 緯度"latitude" in an Imult node

in Imult's RGB channel type control math below:
R channel: sind(longitude)*cosd(latitude)
G channel: sind(latitude)
B channel: cosd(latitude)*cosd(longitude)

than connect normal pass at Imult 's foreground, then you can easy relighting your CG object by adjusting longitude/ latitude in shake!
