I am having trouble finding out how to make one of the layered textures a bump map. I'm trying to make earth and got the pictures from a tutorial. They didn't give very detailed directions though so I was hoping somebodey could tell me how to do make one texture a bumpmap.
Thank You.
Open the attribute editor of the shader that you want to add the bump to. Press the bump mapping flag and look under the utilities section of the create render node window. Select a bump2d node. Now assign the out alpha of the layed texture to the bump value of the bump2dnode.
Good luck,
