Make a Girder (truss support) normal map from an Image

[kat]

Video to accompany "Make a Girder Normal map from an image" tutorial (actually a truss support rather than girder. Ed.) showing the process (no audio) from start in Corel PhotoPaint (any photo-editor will work) to finish (test displayed in Blender - also shows alpha assigned). i.e. creating an image containing greyscale shapes and forms that's flattened and then filtered through a normal map converter, in this instance Njob.
