Some of the following Gimp steps will not be necessary if you used the colored lights approach as you will already have the three color channels combined. | Some of the following Gimp steps will not be necessary if you used the colored lights approach as you will already have the three color channels combined. | ||
Also I like to have backup in case I mess something up so I usually make copies of the original bakes to work with VS using the original. Therefor throughout these steps I am copying or creating new layers as I break the channels apart and when I re-combine them. It's not a necessary step. Unless otherwise noted I am usually working with only one layer selected at a time. Later on when your combining them that isn't necessarily true. But then you have to be sure to only have the layers your working with active or it will corrupt the results. Especially during the channel combining steps where you are "adding" layers together. | |||
