Hi Friends
Recently in an aircraft texturing tutorial I come to know that you can use same bump map that you have made for the aircraft can be used in diffuse and specular color channels???But I know that in diffuse channel you put your painted (I mean the painted color texture) and in bump channel you put the bump map?so what effect one has by putting bump map in specular channel?or is there any other channels that can be used also,this is totally new topic for me,any tut that explains it will be helpful too.
Thanks for your time.
